Magma roots

The problem with “grass roots” as a metaphor is that it reduces its contributors to the miniscopic. Not microscopic, because then you couldn’t see them without a microscope. But miniscopic, meaning they’re small. You have to get down on all fours to eyeball them and say hi.

So I’ve been thinking about alternative meaphors where large movements are involved. For that you have to go deeper. Not into the dirt, because that has connotations of filfth and death. Rock roots is okay, in the sense that serious rock for the most part is solid, or what geologists call “competent”. You can build on it, and with it. The largest slabs of it are “tectonic”.

But maybe we can go deeper than that, below the Earth’s crust. How about “magma roots”? That occurred to me while reading Ron Schott‘s post, Building a Google Earth Geology Layer. Ron is a hard rock geologist who has been a good source of wisdom (and occasional correction) toward my own geology obsessions. What Ron proposes (in both his posts title and its detail) is a great idea — for Google, for the geology field, and for the rest of us.

Ron’s goals are modest in manner and ambitious in scale:

What I’d like to do here, with the help of the geoblogosphere (via the comments to this post, initially), is to set out some goals, examples, and use cases that could guide the development of a Google Earth geology layer. If there’s interest in building on this idea, I’d be happy to set up communications tools, create KML tutorials, or do anything else to facilitate a coordinated effort to develop such a layer. Hopefully, by leveraging the knowledge and efforts of the geoblogospheric community, along with excellent new resources for developing KML, we can make a real start toward building a useful geology resource.

For now, what I’d like to do is to begin to collect best practices/examples of good uses of KML in illustrating geology in Google Earth. I’ll start by pointing out the USGS Earthquake Hazards Program’s collection of Google Earth KML files and another collection of geologic KML resources at San Diego State University. These should give you some idea of the sorts of things that will be possible. Also helpful would be use cases – how would you like to use a geology layer in Google Earth? Suggestions here will offer us guidance as to what the most important elements of a Google Earth geology layer should be.

I’m not a geologist, but I want to do everything I can to help raise this barn. Or, to keep from mixing metaphors, uncork this volcano.

Not long ago as geology goes — nine, ten, twelve millennia — one of the world’s largest lakes covered most of Minnesota, plus much of North Dakota, Manitoba, Saskatchewan, Ontario and a corner of South Dakota. It’s called Lake Agassiz, named after the scientist Louis Agassiz, who figured out the Ice Age (continental glaciation, basically), and whose statue dropped head-first into the concrete in the 1906 earthquake.

Evidence of the late lake s not obvious unless you look in winter, from altitude. I did that while flying west the week before last. Here’s the photo set I shot. Those lines you see in the farmland are old shorelines of the lake. Since it was a glacial lake — a large puddle left by the effect of global warming on the ice cap — these lines I suppose also qualify as glacial moraine. Anyway, interesting shit. To me, at least.

By the way, the straight lines in the shot above are wind breaks made of trees or hedges. (Not sure.). The larger square or rectangular dark areas are woodlots. The setting is a spot almost exactly where South Dakota, North Dakota and Minnesota meet. I believe it is in South Dakota.

By the way, what remains of Lake Agassiz is Lake Winnepeg, Minnesota’s ten thousand lakes (See this comment below for the correction, and a larger number scattered around three provinces of Canada.

This LA Times editorial says,

…when many of Santa Barbara’s most determined anti-drilling activists teamed up to back a deal that would allow an oil company to drill under state waters off the city’s coast, it was a jaw-dropping moment.
Just as surprising, given the deal’s powerful backing, was its collapse Thursday, when the State Lands Commission rejected it on a 2-1 vote. The failure shows that, despite high oil prices that turned “Drill, baby, drill” into a Republican mantra last year, it remains phenomenally difficult to expand drilling in California...
Under the publicly disclosed terms of the deal, Plains Exploration & Production Co., which owns a platform in federal waters just beyond the three-mile limit controlled by the state, would have drilled several wells from the platform into oil reserves on state property. In return, it would have closed that platform, three others it operates off Santa Barbara and two onshore processing facilities by 2022 and donated 4,000 acres of land for preservation. Over the life of the project, the state would have collected up to $5 billion in tax revenues.
Bizarrely, the company and the environmental groups that were parties to the bargain kept the rest of its terms confidential. It is not unheard of for environmentalists to sell out the public interest for political or financial reasons, and no elected official should ever approve a secret deal that affects public resources. The company finally announced that it would disclose the full agreement during Thursday’s Lands Commission hearing, but that was months too late.

To this Santa Barbarian, who loves views of the sea, the oil platforms have their charms. They protrude from the planar Pacific like little square islands with christmas lights. And, as infrastructural studies, they’re rather interesting. It turns out that they’re also welcome offshore habitats, as are scuttled or wrecked metal boats.

Which are worse — oil platforms, or the hills of Los Angeles prickling with pump jacks? Pick your poison. Both bargains are Faustian.

The environmental damage risked, much less caused, by offshore drilling, is not a large part of the whole. Lost in most arguments about drilling in Southern California is the fact that up to hundreds of barrels of crude seep into the ocean constantly there, most of it right by UCSB. It stains the water with long streaks of gray-blue oil, much of it spreading from methane — natural gas — bubblings, some of which are trapped and captured by underwater contraptions. Also lost is the fact that offshore drilling on the West Coast contributes a trivial sum to U.S. energy independence.

Civilization is an open laboratory of trade-offs, with a time horizon that is never geological — and human only to the degree that it considers the wants of the living.

I think the best energy bargains are ones involving sun and wind. But there’s not enough of either to satisfy the energy appetites of a human population that has swelled to many billions. So we must continue to eat the Earth until its dead stuffings fail to sustain us.

After that? Who cares? We’ll all be dead by then too. Maybe some successor species will mine our cemeteries.

On Tuesday I got my first good look into the coal mines of Wyoming’s Powder River Basin. This is literally where the deer and the antelope played, until the human appetite for power began eating it up. Featured are the Jacobs Ranch and Black Thunder Mines. The latter is featured in John McPhee’s Uncommon Carriers. Great reading. Go get it. (The chapters appeared first in The New Yorker.) Black Thunder (that’s it, above) is the world’s largest coal mine. It’s owned by Arch Coal. About its Powder River mines, Arch says,

Arch had sales volume of 99 million tons of coal in 2007 in the southern Powder River Basin in Wyoming, the nation’s largest coal-supply region. This tonnage is produced at Thunder Basin’s Black Thunder and Coal Creek mines. Arch controls approximately 1.75 billion tons of reserves in the PRB.

I also shot Coal Creek, which is on the other side of another huge mine, Jacobs Ranch. Got many shots of that one too. In fact, I have all these shots in RAW, in case anybody wants a high-quality copy.

On departure from Zürich to Paris yesterday the ground was shrowded in gloom and haze, but above it the sky was clear and crystalline. I sat purposely on the left side of the plane to get a view, even though I knew I’d be photographing the scene against the sun, which would be low in the early afternoon on a day approaching the Winter Solstice. Worse, the window looked like it had been cleaned with fine-grit sandpaper. Still, I got some nice shots with my old Tamron zoom and the Canon Rebel Xti (borrowed from the excellent and generous Rebecca Tabasky, a colleage at the Berkman Center).

I’m guessing the plane was about a hundred miles from the shot above. Closer for some of the early ones, and much farther for some of the later ones, some of which feature Mont Blanc, the only peak I could easily identify. I’m hoping some of the rest of you can fill in the blanks.

After Murad Ahmed wrote Citizen journalists told to stop using Twitter to update on Bombay attacks in TimesOnline, and David Stephenson blogged a similar concern, Bruce Schneier responded with Communications During Terrorist Attacks are Not Bad. Specifically,

  This fear is exactly backwards. During a terrorist attack — during any crisis situation, actually — the one thing people can do is exchange information. It helps people, calms people, and actually reduces the thing the terrorists are trying to achieve: terror. Yes, there are specific movie-plot scenarios where certain public pronouncements might help the terrorists, but those are rare. I would much rather err on the side of more information, more openness, and more communication.

I’m sure there was wrong information coming across Twitter during recent California fires as well. But whenever bad things happen — whether caused by bad luck or bad people — good will and good people out-care and out-perform the bad.

The best mainstream media piece I’ve read yet about this topic is Citizen Journalists Provided Glimpses of Mumbai Attacks, by Brian Setzer and Noam Cohen in the New York Times. The first four grafs:

  From his terrace on Colaba Causeway in south Mumbai, Arun Shanbhag saw the Taj Mahal Palace & Tower Hotel burn. He saw ambulances leave the Nariman House. And he recorded every move on the Internet.
  Mr. Shanbhag, who lives in Boston but happened to be in Mumbai when the attacks began on Wednesday, described the gunfire on his Twitter feed — the “thud, thud, thud” of shotguns and the short bursts of automatic weapons — and uploaded photos to his personal blog.
  Mr. Shanbhag, an assistant professor at Harvard Medical School, said he had not heard the term citizen journalism until Thursday, but now he knows that is exactly what he was doing. “I felt I had a responsibility to share my view with the outside world,” Mr. Shanbhag said in an e-mail message on Saturday morning.
  The attacks in India served as another case study in how technology is transforming people into potential reporters, adding a new dimension to the news media.

Actually, a new medium. And a new methodology. And a new way to invest the best, far more than the worst, in human nature.

Got some nice shots of San Francisco and Marin on Sunday, as we flew off to Chicago on the first leg of the trip home from Thanksgiving in California. Actually, my kid shot most of them, since he had the window seat. Shot some other stuff too, which I’ll put up later.

Mount Tamalpias (better known as Mt. Tam) looms in the background, and Mt. Beacon in front of it.

These are a few among the many salt ponds that ring the south end of San Francisco Bay. Once considered and agricultural innovation and an economic boom, the practice of “reclaiming” wild wetlands for industrial purposes is now considered ecologically awful by environmentalists, especially here on the West Coast of the U.S., which has precious few wetlands in any case. Many environmentalists have been working to get Cargill to close the ponds and return the Bay to its more natural state. Cargill hasn’t budged. In fact, <a href=”http://www.cargill.com/sf_bay/saltpond_ecosystem.htm”>Cargill has its own views</a> on the matter, plus some interesting facts about the ponds themselves.

It’s worth pointing out that the Bay is actually one of the youngest features on the California landscape, having flooded within only in the last couple thousand years, as sea levels rose. (Global warming has been happening, in fact, since the last ice age.)

I took this shot two days ago on approach to San Francisco on a flight from Boston. Here’s a set of all the photos I’ve taken of salt ponds, both here and in the desert. And here is the whole set of shots I took from coast to coast. Most were at the ends of the flight, since the sky was undercast most of the way.
