Diamonds And Volcanoes, Oceans And Space

I wasn't sure what to do with this piece on diamonds.  It was interesting - both because of what it said and because it exposed a gap in my knowledge that probably most people know already.  (Did you?)   I tend to think diamonds and their high prices are due to monopoly and marketing.  Young men are cowed into buying sparkling rings by all the hype about diamonds being forever and the made up tradition of diamond wedding rings.  I'm not making this all up, people have studied this.  The article mentions that diamonds weren't associated with weddings until the 1930s.

But I acknowledge that industrial diamonds probably play an important role in society.  From the USGS:
"Because it is the hardest substance known, diamond has been used for centuries as an abrasive in grinding, drilling, cutting, and polishing, and industrial-grade diamond continues to be used as an abrasive for many applications.  .  . Diamond also has chemical, electrical, optical, and thermal characteristics that make it the best material available to industry for wear- and corrosion-resistant coatings, special lenses, heat sinks in electrical circuits, wire drawing, and advanced technologies."
I actually started yesterday's post with the quote below on diamonds.  That's why yesterday's title was  misleading.  The post was going to be bits and pieces of different things that weren't related and not enough to be a post on their own.  But the post evolved and the photos about the Silverlake walk were enough.  So I cut the diamond reference, but forgot to update the title.

So here's what I edited out yesterday:
"Most diamonds come from depths of 90 to 120 miles beneath the Earth’s surface, Smith said. The only reason they are accessible to us today is because they traveled up through the crust millions of years ago, carried along by rare and powerful volcanic eruptions.
But chemical clues culled from the Cullinan diamond and others like it suggest they were forged at even greater depths than most diamonds — about 224 to 446 miles beneath our feet."
- From an LA Times article on what scientists are learning from diamonds about deep in the earth .

I resurrected the post because last night before going to sleep I picked up my next book club volume - Anthony Doeer's All the Light We Cannot See - and read this:
"A diamond, the locksmith reminds himself, is only a piece of carbon compressed in the bowels of the earth for eons and driven to the surface in a volcanic pipe.  Someone facets it, someone polishes it."
I got the same lesson about diamonds and volcanoes from two different sources on the same day.  Did I ever learn that diamonds were spewed out of the bowels of the earth by volcanoes?  Maybe, but if I did, it didn't stick in my conscious knowledge.  But I was getting a message from someone to pay more attention now.

The original LA Times article is about a scientist studying large diamonds for what they tell us about so deep in the earth - a place, the article tells us, scientists can't reach, so these travelers from this distant region of our own planet offer up clues to what else is there.  And the article says there's a lot more minerals than had been previously thought.

This also got me to thinking.  Voyager has travelled about 12 billion miles from our sun,  about how we can send missions to to explore our solar system, but we on earth,  according to the Smithsonian:
"as of January 22, drilling had only reached a depth of 2,330 feet beneath the seafloor."
That's less than half a mile.  The earth's core is 6,371 kilometers (3,958 mi) according to this extreme tech article.    This site has a lot of clickbait, so checked further.  National Geographic says "about 4000 miles" so it's ok.  [There's an interesting graphic representation of traveling to the center of the earth at this BBC page.]


Is it really harder to drill into the earth than to go out into space?  Or is space just more romantic and better sold - like the diamonds - than earth core exploration?  Perhaps it is simply more difficult.  I found lots of articles comparing exploring space to exploring the oceans (where getting to the earth's core seems to begin).  This article from American Progress suggests it IS 'marketing' or at least what has stirred our exploratory imaginations:
"Yet space travel excites Americans’ imaginations in a way ocean exploration never has. To put this in terms [James] Cameron may be familiar with, just think of how stories are told on screens both big and small: Space dominates, with “Star Trek,” “Star Wars,” “Battlestar Galactica,” “Buck Rogers in the 25th Century,” and “2001 A Space Odyssey.” Then there are B-movies such as “Plan Nine From Outer Space” and everything ever mocked on “Mystery Science Theater 2000.” There are even parodies: “Spaceballs,” “Galaxy Quest,” and “Mars Attacks!” And let’s not forget Cameron’s own contributions: “Aliens” and “Avatar.”
When it comes to the ocean, we have “20,000 Leagues Under the Sea,” “SpongeBob SquarePants,” and Cameron’s somewhat lesser-known film “The Abyss.” And that’s about it."
And since this quote mentions 20,000 Leagues Under the Sea, I should mention that a key character in All The Light We Cannot See is reading Jules Verne's classic story in braille.

Forms of Water: Ice, Snow, Clouds, Water

Flying out of Anchorage always offers amazing views of nature.  As we headed south to gather we family over Thanksgiving, I took advantage of my window seat.  Clouds played a big role in the dramatic landscapes today.  But when I thought about the post, it came to me it's mostly about different forms of water - ice, snow, clouds, and liquid water itself.





The tide was low so we could see the rivers in the mudflats white with ice.














There were low clouds over Prince William Sound and they flowed into the lower levels of the Chugach mountains offering contrasts of the white of the snow and ice to the white of the clouds.




At this part of Western Prince William Sound, the water is blanketed with clouds.













But then there was a spot where the land blocked the clouds and in Eastern Prince William Sound there was water.  At this point in the year, the sun stays fairly low on the southern horizon all day and it will get a little lower yet by solstice.  So at 11am or so it looked like a sunset picture.



Then we got these great cloudscapes.  Large clouds rising in colonies from the water.  It reminded me of the dramatic clouds of Southeast Asia, though these clouds were small in comparison.



My son gave me a book on clouds for my birthday and I was reading through it the other day and thinking I should bring it along.  In the end I put it off for when I have more time and fewer books already on the todo list.  But the clouds today made me question that decision.




The water surface was covered with interesting patterns.  It looked, from 34,000 feet like neat patterns on a flat surface.  But I'm guessing if I could seem them from the plane, the water was probably fairly choppy




And it was still spectacular as we cross out of Canadian air space into Washington State.


Leaving as frequently as we have the last couple of years - first with my mother and then with the grandkids - means constantly cleaning up the house so it's presentable before the housesitter arrives.

Sunny and Warm

Crossed over the bridge in Campbell Creek Park off Lake Otis and kids were swimming in the creek. (I was going to say 'cold creek' but I didn't try it.  Maybe with all the warm weather we've had the water's warmer than usual too.)

And in the spirit of all the sun we've been getting, here's a sun flower from a plant our neighbor gave us earlier this summer.  


It said 82˚ (F) on our deck thermometer when I got home this afternoon.  Feeling so lazy.

A Nature Break - Just Relax And Enjoy

We did a short hike along the trail up toward Wolverine Peak Sunday evening.

My favorite part is crossing the creek and watching the water rush by.  So here's a moment out in the woods on the hillside above Anchorage.

Why Do Ponds Freeze Differently?

I'm afraid this post raises questions rather than answering them.   Limited time and physics savvy make this necessary.  But there are some links to offer a little bit.

These are pictures of frozen puddles I saw at Denali.  And naturally I wanted to know why they were so different.

First this one in our campsite the first morning.  Why did the ice freeze in the long roundish spikes?



Second, why did this puddle freeze round, but then have more angular geometric patterns in the middle?



I'd note, the next morning, there was no more ice.  In fact these two puddles were gone altogether.  Just depressions in the soil.





Why is this puddle in the tundra frozen yet clear?



While this one is frozen by clouded?



The internet offers some insight into the freezing of puddles.



Here's  Story of Snow's explanation of why puddles get these curvy lines as they freeze.   Here's an excerpt (it has good illustrations too.)
"The thick, continuous curves show places where the ice is thicker underneath. Other lines may mark the boundary where the ice thickness changes. The ice thickness varies because of the way the meltwater drained below the ice. The sketch below shows a puddle just starting to freeze. We are viewing a cross-section, and the ice is coming in from the edge."

There's some conjecturing on the geometric patterns on the ice in this discussion board.

I could only find posts on why ice cubes are sometimes clear and sometimes cloudy.  Here's part of an explanation at Today I Found Out:
"The answer to this mystery lies in the temperature of the water. You see, at room temperature there are a lot of impurities that are dissolved in regular old tap water. And as you may recall from high-school chemistry, the warmer water is, the more of a given substance it is possible to dissolve in it. For example, sugar has very weak molecular bonds that require only a small amount of energy to break. Thus, as you supply water with more energy by heating it, the amount of sugar you can dissolve within it increases and vice versa. You perhaps have noticed this phenomenon when sweetening hot tea vs. cold, or after letting a sugared cup of coffee get cold, with the sugar dissolving fine when it’s hot, but showing up at the bottom of your cup when the coffee gets cold. This is essentially what happens with ice. As you cool the water, all of the impurities that were happily dissolved in it at room temperature separate themselves from the liquid and become visible."
It goes on to explain why the cloudy part is usually in the middle of the ice cube.  I suspect this could explain the differences between the puddles that were clear and that were cloudy.  But I'm not sure.

Actforlibraries  explains why puddles freeze at different temperatures.  This one is short and easy to follow.

UCSB Science Line explains why water freezes on the surface of a lake, but not below.  That seemed pretty obvious (the air temperature is colder than the ground temperature.)

Another article on the Thermodynamics of Freezing Puddles in Autumn-Winter Period looks at sea water.  I could only see the abstract and decided not to pursue the whole article since it was about fresh water.  I also wasn't sure I'd understand much of it, but someone else might find it interesting.

There's even something called an ice spike which sticks up out of the water.  I've never seen one and they're rare it says

Standpipes - You've Seen Them, But Do You Know What They Do?


Walking San Francisco streets last weekend, I was struck by the pipes coming out of the walls of buildings.  Things I'd seen many times but never really paid much attention to.  So, camera in hand, I paid more attention.  They come in lots of varieties and they're labeled 'standpipe' or sometimes 'dry standpipe.'





From Fireking:
Wet and Dry Standpipe Systems 
Description: A Standpipe is a type of rigid water piping which is built into multi-story buildings in a vertical position, to which fire hoses can be connected, allowing manual application of water to the fire. Within buildings standpipes thus serve the same purpose as fire hydrants. Well maintained fire standpipe systems are highly reliable and provide people protection as well as property protection. Fire King Fire Protection, Inc. specializes in Inspection, Testing and Maintenance of Fire Sprinkler Systems. 
Dry standpipe: Dry standpipes fixed into buildings, the pipe is in place permanently with an intake usually located near a road or driveway so that a fire engine can supply
water to the system. The standpipe supply pipe extends into the building to supply fire-fighting water to the interior of the structure via hose outlets, often located between each floor in stairwells in high rise buildings. 
Dry standpipes are not filled with water until needed in fire-fighting. Fire fighters often bring hoses in with them and attach them to standpipe outlets located along the pipe throughout the structure. 
Wet standpipe: Wet Standpipes are filled with water and is [sic] pressurized at all times. In contrast to dry standpipes, which can be used only by firefighters, wet standpipes can be used by building occupants. Wet standpipes generally already come with hoses so that building occupants may fight fires quickly.





And after reading about the standpipes, I realized I needed to get a picture of the hoses inside a building.  Fortunately I was in a building and found the hose.



A 2007 NYTimes article, after a fatal Deutsche Bank fire, caused by bad standpipes, went on to explain standpipes and their maintenance in more detail.
"A typical standpipe system begins with the street-level connection, known as a Siamese, which is connected to pipes that run vertically or horizontally inside the building and connect to vertical pipes that run to the top of the building. The vertical pipes are what most people think of as the standpipe.
Standpipes are required in all buildings in New York City that are more than 75 feet tall, or higher than six stories, Kate Lindquist, a spokeswoman for the Buildings Department, said.
The vertical pipes, often painted red, are exposed in a building’s stairwells, and there is a connection on each floor to which firefighters can hook up hoses.
Water, and water pressure, are supplied by the Fire Department. When there is a fire in a building equipped with a standpipe system, the first engine company to arrive connects a hose to the nearest hydrant and another to the Siamese connection in front of the building, according to Firefighter Jim Long, a department spokesman. The pumper boosts the pressure of the water being fed from the hydrant to the Siamese and then to the vertical standpipe."
It also says standpipes were first used in New York City.
". . . standpipes originated in New York City about the time of the Civil War, along with sprinkler systems, 'as buildings grew taller and as the philosophy of firefighting evolved.' Before that time, he explained, 'most fires were fought from the outside.'”

A Bit of Exercise

The sun's been finding big holes in the clouds that dumped a couple of inches of rain yesterday here on Bainbridge Island, so I grabbed my daughter's bike and moved my legs.  I stopped at Manitou Beach, a tiny stretch of rocks and shells and driftwood with a mirage of downtown Seattle floating out in the distance.



Looking closer to in.






A driftwood shellf.

A stray rain cloud blew by while I was stopped at the beach so I decided to head back.  But the sun was out again on the way home.  It's setting now, still light, but the temp has dropped about 20 degrees since earlier this afternoon.

Seattle Shots Before Limping Back To Anchorage








It's been a good almost two weeks with both kids and the grandkids together for Thanksgiving in Seattle, but my body is not 100%.  My granddaughter's gift of a cough has slowed me down.














This was after a trip to Elliot Bay bookstore the other day, getting back to the ferry.



Taking my son and his family to the airport yesterday we went through total fog down to the water on the ferry, to surreal sun pierced fog with giant tree shadows.  But I was driving so can't show you that.   This was later.  Seatac was in the blinding, early morning sunshine, but going back downtown, there were intermittent pockets of sun and fog.






And unnatural fog.


















Here's a different Seattle view from the ferry.













And for people like me, who have searched for unsweetened cranberry juice, it exists.  My son-in-law had some students who make it at Starvation Alley Farms.  It's organic, and I need to mix it about 1/5 cranberry juice and 4/5 water. Mostly they sell it to bars that use it for mixed drinks, but it's also available in a few markets in the Northwest.  I know the name's a bit strange for a food product, but that was the name of the farm before they bought it.






Cards by Lynn




We're excited to get home for the Anchorage International Film Festival that starts Friday.  I'm taking
these last couple of days to catch up a bit on important things that haven't gotten done yet.  Like writing thank you notes to friends of my mom's.  I feel bad about how long this is taking me to do, but it's hard, and I want to let people know how important they've been in my mom's life as well as mine.

And to try to get rid of this cough.

"Even one inch of rain in Los Angeles can generate more than 10 billion gallons of runoff."

One of the most important ideas I've encountered in recent years, was in E.O. Wilson's The Future of Life He talks about how the earth naturally cleans the water and the air and how when humans cut trees, fill in wetlands, and pave the earth, we interfere with that natural infrastructure.  Then when we try to replicate what nature did for free, it costs us a fortune.  Wilson cites a 1997 study that estimated the annual value at $33 trillion.

Ecosystems services are defined as the flow of materials, energy, and information from the biosphere that support human existence.  They include the regulation of the atmosphere and climate;  the purification and retention of fresh water;  the formation and enrichment of the soil;  nutrient cycling; the detoxification and recirculation of water;  the pollination of crops;  and the production of lumber, fodder, and biomass fuel. [p. 106]
Flying into LA
So when I read this LA Times piece, I thought I should note it as one more example of how humans have unknowingly tampered with the natural regeneration and cleansing system that the earth provides.  In this case replenishing the aquifers. 
"As we have paved our cities, covering the land with impervious concrete and asphalt, less and less rain is recharging urban groundwater; it’s running off all those hard surfaces into storm sewers and out to the ocean. Every year, hundreds of billions of gallons of storm water wash into Santa Monica Bay, Long Beach Harbor and the San Francisco Bay. Even one inch of rain in Los Angeles can generate more than 10 billion gallons of runoff."
Think about the costs of building desalination plants, while LA is pouring hundreds of billions of gallons of fresh water into the ocean.  I don't know if that total is all the water that goes into the ocean or just the amount that would have stayed in the soil and/or drained down into the aquifers.

Up to now, our capitalist system hasn't applied the cost of such externalities of our economic activities. (For a graphic economics explanation of externalities, see this Khan Academy video.)  So when contractors bulldoze trees and replace them with a building and parking, the cost of the lost air cleansing and water retention those trees did is not not reflected in the price of the new building. Instead the cost is born by society as a whole.  This means that businesses have an incentive to destroy the environment, because doing so doesn't affect them. 

Unless there are strict environmental protections in place and/or government imposes some way to charge for the externality.  A revenue neutral fee on carbon is, for example, seen by many as a way to put the cost of global warming into the price of carbon based products.   Here's an example of how a carbon fee would work.

Meanwhile what I'd like lots of people to understand is this concept of the natural recycling the earth does and how messing with those processes really is damaging a very important natural infrastructure that has great impacts on the earth and the humans that live on earth.  The pavement in California is just one example.  By the way, the author calls for replacing it with more porous material that will allow rainwater to percolate down to the aquifers.

At Least Eight Appeals Received By DNR On Chuitna Water Reservation Decision

I've been planning to do an update on the Chuitna Decision, but I needed to go through it carefully and figure out reasonable questions.  I thought I'd ask David Schade, the head of the Water Division, who signed the decision and then some of the other interested parties. 

But life happens and I only got through to David today.  We haven't had a chance to discuss my questions, but he did tell me that he'd been told there were eight appeals by late this afternoon - people had 20 calendar days to get appeals in, and the decision was on October 6.  He hadn't seen them yet, so he didn't know who submitted them. 

Here are some of the kinds of questions I had:

1.  Was this decision a postponement of the decision or a denial?  It seems to me that at one point the decision says that the Upper and Central fork portions of the Middle River, which are in the proposed mining area, are ripe for decision yet because the the mine's water reservations aren't complete.  That sounds like things are postponed.  But elsewhere it says the reservations have been denied, which sounds final. 

2.    What is the state of PacRim’s water reservation applications?  Different references were made to their applications but it wasn't clear where they were.
- not ready to be submitted because not enough info?
- have they submitted incomplete applications?  What does this mean?
- if submitted, when were they submitted?


3.  The Department finds that it is in the public interest to allow the PacRim permitting review process to be completed, and therefore that it would not be in the public interest to issue a reservation of water on the Main or Middle Reaches of Middle Creek/Stream 2003 at this time.
Is this a logical fallacy?  If one is in the public interest, does that automatically mean the other isn’t?  What this does seem to be saying is that if the reservation is issued, the permitting process would end.  


4.  Can PacRim really close down the Middle Fork above the Lower Reach and divert the water around and back to the Lower Reach and this won't harm the salmon?  Is there a difference between naturally flowing stream water and water that goes through culverts and how does that impact the quality of the water when it gets returned to the natural water way?  And how long would the water be cut off from the Lower Reach while this is being constructed?  Or are those questions people are still waiting on answers for?


There are more questions, but this gives you an idea.  The Oct 6 decision is linked at the earlier post on this.

Japanese Garden, Lilies, Birds, And Water



We visited with an old friend we hadn't seen in years.  She recommended the Japanese Garden in Van Nuys as the meeting place. 


Wow, we didn't even know it existed.  It was a great place to walk and talk. 

We know the Japanese Garden in Portland fairly well, having lived close to it when we were in that city for six months.   This one is totally different and interesting in its own way.

Lots of birds.  Like this osprey. 




And lots of lilies in a long flat rectangular lily and lotus pond.





And a wonderful way to catch up on lives. 







Not much time now.  Headed for the airport and Seattle before we get home.  If all goes well, we'll meet our granddaughter's plane in Seattle, which is why we're on such an early flight.  (Well, an 8 o'clock flight doesn't sound so early, it's getting to the airport on time that's the killer.)

So here are some of the pictures.

Lotus































Snowy Egret















There's an American Bittern sitting on the rock







There's also a very big modern building on the grounds that seemed too big and the style too space-agey for a Japanese Garden.  It turns out the garden is really part of a large water reclamation plant which sits directly next door and the building is for that rather than the garden. 


I didn't take any pictures of the building except of the garden through the walkway around the building.


The AAA explains this relationship:
"The Japanese Garden at the Tillman Water Reclamation Plant, 6100 Woodley Ave., is a water-treatment facility highlighted by a 6.5-acre Japanese garden."



It's a stark contrast between the garden and the plant which abut each other. 


And, apparently, I'm not the only one who thinks the building (not the plant, but the building which I didn't take pictures of) is space agey. From a Memory Wikia:
"The location can also be seen in episodes of Knight Rider (1986), Murder, She Wrote (1993), Mighty Morphin' Power Rangers (1995), L.A. Heat (1997), Charmed (1999), and Numb3rs (2009) and was featured in the action comedy Dead Heat (1988, starring Joe Piscopo), the crime drama Rising Sun (1993), the science fiction film CyberTracker (1994), the action film Red Sun Rising (1994), the comedy Bio-Dome (1996), the comedy Austin Powers: International Man of Mystery (1997), the thriller Most Wanted (1997), the science fiction thriller Terminal Error (2002, with Marina Sirtis and Michael Nouri), and the science fiction film Sci-Fighter (2004).

Dave Schade To Sign Chuitna Decision After Hours Tonight - To Be Posted Tomorrow Morning - Memos and Maps

As a blogger who works from home or wherever I happen to be, but basically without colleagues, I sometimes feel like maybe something happened but I didn't know about it.  I did google around to see if the Chuitna Citizens' Coalition application for an Instream Flow Reservation had been decided on before posting last night that the decision was due today.

This morning I checked the DNR webpages and also the Coalition's Facebook page, but there were no announcements.  I called the Chief of the Water Resources Management Unit, Dave Schade, who is the person who has to sign the decision.  His phone said he's out of the office for a week or so.  So I tracked down someone else and left a voice mail.

Elizabeth Bluemink called me back a bit ago to say that Schade will sign the document around 8pm tonight and that it would be posted tomorrow morning.  In the meantime, she's sending out copies of documents that are related but don't talk directly about the decision.

So I've posted them on Scrbd and embedded them below so you can look for clues to what the decision will be.

1.  A memo to the Commissioner of DNR called a primer on Types of Water Use.  This is sort of a Water Use for Dummies version that's pretty straightforward.  As I read it - having been to the objections hearing, but without any specific expertise here - it sounds like the opposition's arguments that the application should be simply denied was a lot of smoke.  But I'm sure there are subtleties here I'm missing.  Judge for yourself. 

2.  A list of water reservations certificates in Alaska.  There are 75 bodies of water listed (mostly rivers, then creeks, then lakes) and 131 certificates.

3. A map of the Chuitna Coal Mine project - which I can't totally make sense of.  I think my problem is that this is about the mine and doesn't identify the area where the Chuitna Citizens' Coalition is applying for the IFR.  But maybe I'm just missing it.

4.  The memo sent out to notify potential objectors to the reservation that the hearing would be held.  I don't have that up in this post, but I did post it before the hearing and have it at Srbd already.

Ferries First, Then Come The Bridges

Yesterday I had a chance to meet John Duffy, the former manager and planning director of Mat-su.  I asked him about his thoughts on the Knik Arm bridge and the ferry that has been a white elephant for the borough since building a ferry dock on the Anchorage side never happened.

His response was that the ferry was a good idea and the Knik Arm bridge is a bad idea.  But the comment he made that most caught my attention was that "there has never been a bridge built that wasn't preceded by a ferry."   He even volunteered to give me $100 if I could find one.

Did he have any backup evidence on this?  Is there a book on this?  An article?  Is there a way to find this on google without checking bridge by bridge?  He didn't know of any, but he said he just knew this because he worked in this area.  He did add that all the contractors who looked at building the Knik Arm bridge said that they needed a ferry to get supplies, employees, and inspectors across the gap while building the bridge, that they weren't going to do the five hour round-trip drive.  That made sense.

OK, I realize that while Duffy didn't initiate this project, he did inherit it and promoted it for a while. I'd never heard before that bridges don't get built unless there are ferries first.  If this is true, what does it suggest about the future of the Knik Arm bridge?  Duffy's role might give him an incentive to make it look like a good deal, but it also gives him some inside knowledge.  And, as I said, the idea that bridges don't get built unless there are ferries first is new to me, and I suspect to others.   Of the many projects in Alaska that haven't worked out, this one had acquired a pretty pricey boat for nothing and merely needed a port on each end - a minor task compared to, say the Knik Arm bridge project.  If people had supported it strongly, it could have easily happened.  The question is why, really, did the support evaporate?  (I don't have the answer today, but it's something we should be asking.)

But I'm am going to offer what I've found about the idea that bridges are always preceded by ferries.


Googling The Link Between Bridges And Ferries

So I started googling.  Things like 'bridges preceded by ferries,"  which got a number of articles about specific bridges in the US.  But I wanted a larger selection.  So I looked up "10 biggest bridges in the world."  That got me lots of the ad-laden list sites.  So I opted for Wikipedia which gave a list of countries and lists of bridges in those countries.  But they tended to only talk about the bridge and not what preceded the bridge.

I changed my strategy a bit.  Once I got a bridge name, I googled for the river plus crossing with ferries.  This got ferries for every bridge I looked up.  I've got those below.  Of the 15 or so bridges I looked up, I didn't find one that wasn't preceded by ferries.  That's a small sample size, but I looked at bridges in different parts of the world, old ones, new ones, big ones and small ones.  I also have examples of bridges crossing different bodies of water - mostly rivers, but also bays, lakes, fjords, and canals. 

A ways into my search, I did find a general statement about bridges and ferries (and fords.)

From an 1898 book titled Science and Industry, Vol II
"Barring these disadvantages, fords and ferries are adequate for the needs of a thinly settled community;  but, as population and traffic increase, there arises a demand for a safe and certain crossing of streams, whatever the state of weather and water.
This demand always precedes the bridge-building period."


Why Does This Matter?

Why am I making such a big deal about this?  We've got a well paid commission that is working to set up the Knik Arm bridge.  Many people think there is no need for such a bridge.  The Mat-su Borough attempted to develop a ferry at the same location.  They got a great deal on an experimental ship built by the US military and they built a ferry terminal on the Mat-su side.  But they couldn't get Anchorage to build a site on the Anchorage side.

Mat-su finally gave up and put the ferry up for sale.

I had assumed the Anchorage side didn't want the ferry because they were pushing the bridge and didn't want the competition.  But the point Duffy was making was that you need a ferry service to demonstrate the need before you build a bridge.  His point was that every bridge over water was preceded by a ferry.  The Science and Industry text says that outright, but it's an old text.  Below is a list of 15 bridges around the world.  Every one I looked up was preceded by ferries.

Not only are ferries, apparently, important as a first sampling test of the need for a bridge, but Duffy points out that to build a bridge, you need ferries to cross the body of water to take materials, employees, and inspectors.


15 Bridges That Were Preceded By Ferries

1.  SFChronicle:
"Ferries on the San Francisco Bay predate cable cars in the city by nearly 50 years, starting with John Reed, who ran a sailboat from Sausalito to San Francisco in 1826. His business didn’t last long. The American Indians, who paddled across the bay, were faster and much more reliable.
Regular ferry service started in 1851, and the popularity exploded in 1907, when several ferry companies consolidated into Northwestern Pacific (taken over by Southern Pacific in 1928). Southern Pacific’s 43 boats in 1930 were reportedly the largest ferryboat fleet at the time in the world.
The local ferry companies aggressively fought the construction of the Golden Gate Bridge and Bay Bridge, and they were financially smart to do so. The popular bridges mortally wounded the ferry business, and the final transbay ferry journey of the era was completed in 1958."

The push for Island bridges
Grand Island was purchased from the Senecas in 1815. Forests of oak trees drew settlers for the Island's valuable lumber. Farms then flourished and the Island became a popular summer resort with sprawling, gracious estates, private clubs and summer homes. It officially became a town in 1852. Two ferries provided transportation to and from the Island before the bridges were built. One launched from the former Bedell House in Ferry Village and the other from the site of the current Byblos Niagara Resort & Spa.
Luther's grandfather, Henry Long, went to Washington, D.C., in 1898 to make a case for bridge construction, but he died in 1925 without seeing his dream come true. A decade later, Island schoolchildren were bused to the South Grand Island Bridge for its grand opening, where noted urban planner Robert Moses and other dignitaries joined in the celebration in 1935. Grand Island Boulevard, then called the Express Highway, had been built in 1933-34, Luther said, to connect the two bridges. The Congregational Church was torn down to make room for the highway to come through. "The second set of bridges didn't come 'til the 1960s," she explained. "But there certainly wasn't the flow of traffic that we have now."

1906 – 1910: Working Out the Bugs
In March McGilvray reported that the bridge had run perfectly since February 6, handling two hundred to three hundred teams of horses and thirty thousand people a day. He estimated the cost of operating the bridge, including the $4,000 in interest on the bond, at $10,578.31. It may not have been as big a savings from the ferry operation as anticipated, but McGilvray’s spin on the numbers illustrates the bargain that was the bridge: it cost the city “one-fifth of one cent per passenger for operation, maintenance, interest, and power.” He closed his report with a request for the city to install a telephone in the ferry car so its operator could call for help should the car break down in the middle of the canal. It was not granted.
4.  Idaho government webstie talks about ferries in Idaho
In the late1800’s there were hundreds of ferries operating throughout the state, but by the early 1900’s the business began to disappear.  With the population growing, it made sense to build bridges across the most traveled routes.  Once a bridge spanned the river, there was no need to have a ferry.
5.  Columbia River Bridge at Astoria, Oregon:
“The Columbia River span ended the last operating ferry service along the Oregon Coast Highway. The use of ferries at the mouth of the Columbia River began in 1840 when Solomon Smith, Astoria’s first schoolteacher, lashed two canoes together and carried passengers and cargo across the river.3 Ferries intermittently served the area into the beginning of the twentieth century. When the Columbia River Highway (US 30) opened a direct overland link between Portland and Astoria in 1915, automobile traffic through Astoria rose, creating pressure for more dependable ferry service. Seeing opportunity, Captain Fritz Elfving established the first commercial auto ferry service in 1921, when the Tourist I made her maiden voyage. For forty years ferries kept the traffic moving, but there were some drawbacks. For one thing, they were slow. In good weather the 4.5-mile trip took half an hour. Since the boats could hold only a limited number of vehicles, motorists often endured long waits in heavy traffic.”
6.  Chesapeake Bay.
Were there any Chesapeake Bay car ferries?
Why yes, there were once a number of ferries that crossed the Chesapeake, and they transported automobiles and trucks from one side to the other. They were quite popular for a time, actually.
As an example, the Virginia Ferry Corporation operated ferries that crossed the mouth of the Chesapeake Bay. They departed from Little Creek (on the border between Norfolk and Virginia Beach) on the western shore to Cape Charles and Kiptopeke Beach on the Virginia Eastern Shore. The heyday for this corporation wasn’t very long. It ran ferries in the years after World War II and into the 1960’s according to the Chesapeake Bay Ferries website.
A much longer ferry tradition existed further up the bay in Maryland. Ferries existed between Annapolis and Kent Island as early as the nineteenth century. They were probably carrying automobiles by the 1920’s or 1930’s according to the Roads to the Future’s Chesapeake Bay Bridge History. Several lines and operators existed between the Maryland Eastern Shore and the larger portion of the state. These included the Claiborne-Annapolis Ferry operated by a private company and the Sandy Point-Matapeake Ferry operated by the State of Maryland
Why aren’t there any Chesapeake Bay car ferries?
That’s another question I often see in my query logs. The answer is simple: Bridges. The Chesapeake Bay Bridge Tunnel opened in 1964, connecting the two shores of Virginia with an innovative combination of bridge and tunnel segments. Maryland also connected its shores with the Chesapeake Bay Bridge in 1952. They weren’t too original with the names, though. This one is just a bridge, no tunnel, as the name clearly states.
The ferries disappeared soon thereafter at both locations. They simply couldn’t compete with the bridges. It might take an hour or two to cross the Chesapeake Bay using a ferry after figuring in waiting, loading, sailing and unloading. It took just a few minutes to drive across a bridge, and travelers didn’t have to worry about sailing times either. Ironically the traffic on the Chesapeake Bay Bridge can get so bad on summer weekends that a ferry is starting to sound pretty attractive again.

7.   From Gulflive, the bridge at Fort Bayou, Mississippi:

Older generations know not to take for granted some of our modern bridges, especially the four-laned ones. In generations past folks often had to rely on ferries to cross bodies of water.
One of the earliest exits out of Ocean Springs was north on Washington Avenue across Fort Bayou. Franco's Ferry came to be operated there by 1875.

Quoting from a book by Chris Wiggins the article continues:
"Ferries came in all sizes and descriptions," wrote Wiggins. "For crossings on smaller bodies of water, a rope or cable ran from one bank to the other. "The ferry guided along this and was pulled by cranking on a winch. For larger crossings a ferry could be propelled by a boat and motor attached to the ferry and no permanently moored cable was required. This was the case across the Pascagoula River, from Gautier to Pascagoula.
"The ferry was operated under a license issued by the county, and public documents provide a record of the rates. In 1893 the fare was: one man on foot $.05, man and horse $.10, man and horse and cart $.15, each driven horse or cow $.02. Interestingly, when the first bridge was completed to replace the ferry in 1901 rates dropped for humans. A man on foot now cost only $.01, but herded animals didn't get a break."
Wiggins noted that the first Fort Bayou Bridge was worn out by 1929 and a new one was constructed. It, like the first one, opened and closed with a swinging span. In 1985, the third and now existing bridge was built. It opens with a draw-bridge (lifting) mechanism, a faster apparatus."

8.  Lake Washington (Seattle Times):
"IN 1939, THE COUNTRYSIDE EAST OF LAKE WASHINGTON WAS FOCUSED on the little market city of Kirkland. In town, chicken ranchers and dairy farmers could buy seed and feed, get a tooth pulled, and stock up on groceries. Every hour, the lake ferry's arrival pulsed trucks, cars and foot passengers through town. But five minutes outside of Kirkland, the Eastside grew sleepy, almost primitive, dotted with worn farmhouses along muddy lanes. The King County Housing Authority worried about rural poverty on the Eastside -- ramshackle houses and poor sanitation.
    To the south, Bellevue was not really a town at all in 1939. "There was no 'there,' there," joked locals, thinking of the handful of stores along Main Street and the endless fields of berries and vegetables. Bellevue was a sprawling, unincorporated district best known for its Strawberry Festival. Along the lakeshore, there were a few elegant homes amid the rustic summer cottages of Medina and the Points -- the Gold Coast of the future.
    But from Bothell to Renton, lake to mountains, the Eastside dozed on gentle country time.
   As the 1940s began, two events awakened east King County to different futures: construction of the first bridge to span Lake Washington and dramatic industrialization of the Houghton lakeshore, in what is now south Kirkland. The revitalized Lake Washington Shipyards would skyrocket on the wartime homefront, only to sputter and fade. But the bridge would turn the Eastside toward a suburban future, and pulled the momentum of growth south from Kirkland to Bellevue."

9.  Istanbul - crossing the Bosporous, from Wikipedia:
Boats have traversed the waters of the Bosphorus for millennia and until the opening of the first Bosphorus bridge in 1973, were the only mode of transport between the European and Asian halves of Istanbul. They continue to serve as a key public transport link for many thousands of commuters, tourists and vehicles per day.

10.  Khabarovsk, crossing Amur River, from Wikipedia
In 1916, Khabarovsk Bridge across the Amur was completed, allowing Trans-Siberian trains to cross the river without using ferries (or temporary rail tracks over the frozen river in winter).
11.  Panama Canal -  Bridge of the Americas, from Wikipedia
"From the beginning of the French project to construct a canal, it was recognised that the cities of Colón and Panamá would be split from the rest of the republic by the new canal. This was an issue even during construction, when barges were used to ferry construction workers across the canal.
After the canal opened, the increasing number of cars, and the construction of a new road leading to Chiriquí, in the west of Panama, increased the need for some kind of crossing. The Panama Canal Mechanical Division addressed this in August 1931, with the commissioning of two new ferries, the Presidente Amador and President Washington.[2] This service was expanded in August 1940, with additional barges mainly serving the military.
On June 3, 1942, a road/rail swing bridge was inaugurated at the Miraflores locks; although only usable when no ships were passing, this provided some relief for traffic wishing to cross the canal. Still, it was clear that a more substantial solution would be required. To meet the growing needs of vehicle traffic, another ferry, the Presidente Porras, was added in November 1942.  [emphasis added]

The Bridge Project

View on Bridge of the Americas
The idea of a permanent bridge over the canal had been proposed as a major priority as early as 1923. Subsequent administrations of Panama pressed this issue with the United States, which controlled the Canal Zone; and in 1955, the Remón-Eisenhower treaty committed the United States to building a bridge.
.  .  .
The inauguration of the bridge took place on October 12, 1962, with great ceremony.

12.  The London Bridge:
"Until Medieval times, the only way to cross the Thames from London on the north bank to the southern suburb of Southwark was by ferry or a rickety wooden bridge. In 1176 all that changed. After successive wooden bridges were destroyed by fire, Henry II commissioned the building of a permanent stone crossing. It took 33 years to complete and was to last – give or take repairs and remodelling – more than 600 years."
I kept looking for different bridges to see if I could find ones that didn't have ferry service first. I looked up bridges built after 2000 to see if new bridges were different.

13.  I found a bridge in Fort Lauderdale, Florida - the 17th Street Bridge - and the history didn't talk about a ferry, but when I looked up "Broward County ferries" I found this
"The fort was later moved to Tarpon Bend, and then to the barrier island near present-day Bahia Mar. A trading post established in the 1890s by Frank Stranahan (1864-1929) at a ferry crossing of the New River became the nucleus of the city of Fort Lauderdale.[3]"
 I don't know that that specific bridge in Fort Lauderdale had a ferry first, but crossing the New River was first done by ferry.   I don't think this bridge will get me Duffy's $100.

14.  I looked for African bridges and found the Mkapa Bridge between Tanzania and Mozambique.
After a lot of poking around I found this (not quite grammatical) evidence that it was preceded by ferries:
"El Nino resulted in a severe flood in 1998 causing considerable loss of life and property
and use of   government rescue helicopters. The Tanzania Essential Health Intervention
Project (TEHIP) as did construction of a tarmac road from Ikwiriri to Mkapa Bridge
which imporvied [sic] the economy of Ikwriri and saved lives and property, the bridge had severe consequences for businesses and livelihoods dependent on the old ferry service." [emphasis added]

15.  Here's a bridge I randomly picked from the Wikipedia list of bridges in Norway:
"Ship services in Nordhordland started in 1866, and in 1923 the first car was purchased.[5] A car ferry service between Isdalstø in Lindås and Steinestø in Åsane on the mainland was established on 7 July 1936.[6] A plan was launched whereby all traffic from Nordhordland would be collected in one place and transported across Salhusfjorden to Åsane. By moving the ferry quay from Isdalstø to Knarvik, the length of the ferry service could be reduced. However, the fares would be kept the same and the extra revenue used to finance a bridge from Flatøy to Lindås.[7] This allowed the Alversund Bridge to open in 1958, and the ferry service from Flatøy and Meland to move to Knarvik."

Some Possible Exceptions

Finding a bridge that wasn't preceded by a ferry is a little like looking for the black swan.  Not finding one doesn't prove they don't exist and there are too many bridges in the world for me to check them all.

There may, however, be some categories of bridges that were not preceded by ferries.  I was looking at a bridge over a man-made lake (caused by building a dam) in Malaysia.  While I can find evidence that there are ferries on the lake, they appear to be more for tourists than traffic.  But I haven't been able to find out how people crossed the river that got dammed before the dam. Probably by ferry in the beginning.  But so far haven't been able to document that.  The river that was damned was the second longest in Malaysia.  But there was a river there before the lake and there was a road. And the road had to cross the river.  Maybe an old bridge and before that a ferry?  Needs more research. 

I also checked on the bridge over the River Kwai in Thailand.  I can't find any real evidence that there was or wasn't a ferry over the river.  But it's possible this part of this river had no ferry.  Since it was used by the Japanese to make a shorter route from Thailand to Burma, they weren't serving local travelers, and weren't concerned about traffic over the bridge, or about the cost of the bridge.

The second case is not a model one would use to justify a bridge without having a ferry first.  The cost of the whole railroad (including this bridge)  in human lives and suffering  resulted in 
"111 Japanese and Koreans. . . tried for war crimes because of their brutalization of POWs during the construction of the railway. 32 were sentenced to death.[3]"[Wikipedia]

I imagine there might be some bridges built out there that didn't have ferries first.  But I'm guessing those bridges were built not to meet the needs of the local folks but of some others who would be advantaged by the bridge.  Like the Japanese railroad bridges in Thailand in WW II.   And I'm guessing like the Knik Arm bridge here in Anchorage.

California Water Savings: “We never thought [conservation] was a bad thing."

Every change has consequences.  From the LA Times:
 ". . .  in a paradox of conservation, water agencies say the unprecedented savings — 31% in July over July 2013 — are causing or compounding a slew of problems.
   Sanitation districts are yanking tree roots out of manholes and stepping up maintenance on their pipes to prevent corrosion and the spread of odors. And when people use less potable water, officials say, there’s less wastewater available to recycle.
   Water suppliers, meanwhile, say the dramatic decrease in consumption has created multimillion-dollar revenue shortfalls. .  . 
 
   “It’s unintended consequences,” said George Tchobanoglous, a professor of civil and environmental engineering at UC Davis. “We never thought [conservation] was a bad thing. Every citizen thinks he or she is saving mankind, and I’m sympathetic, but it just so happens that our basic infrastructure was not designed with that in mind.”
 
. . .   Shorter showers, more efficient toilets and other reductions in indoor water usage have meant less wastewater flowing through sewer pipes, sanitation officials say. With less flow to flush the solids down the system, those solids are collecting and can eventually damage pipes.
   “The costs that we’re going to face due to corroding pipes is going to be astronomical,” Tchobanoglous said. “It’ll dwarf everything else.”

Climate change costs are going to be much greater than anyone has really anticipated.  Every change will have hidden costs because the infrastructure was designed to be used differently.  The more we cut down on carbon use now, the less staggering climate change will be.  The costs of cutting back are tiny compared to the costs of not cutting back. 

The president is talking about glaciers and saving them for our grandchildren to see.  But since most people in the world have never seen a glacier, losing sightseeing opportunities is the least of the problems global climate change is bringing.  It's the hidden, unforeseen things like the impact of less water in the LA sewer system that will eventually cost people in convenience and in dollars.
