How about just making mesothelioma the state disease?
The California state rock is serpentine (correct name, serpentinite), which comes in many varieties, some which contain asbestos, which doesn’t get dangerous unless you grind it up and spread it into the air. Just sitting there, as it does through much of California and in other parts of the world, serpentine is mostly a greenish… Continue reading

Dig your Ordovican great-Xth granddaddy/mommy
Or let the paleontologists dig it for you. That’s what a team led by Yale researchers did last year in southeastern Morocco’s Lower and Upper Fezouata Formations. The result is covered by LiveScience in Oldest Soft-Bodied Marine Fossils Discovered . Specifically, “The animals represented by these newly discovered fossils, including sponges, annelid worms, mollusks, and… Continue reading

Hoover Dam Bypass Bridge fly-by
The shot above, made on Sunday out the window of a plane on approach to Las Vegas, comes three and a half years after this shot, which I took from the ground at Hoover Dam. Here’s a whole set of the fly-by. Not much of the dam shows. The Colorado River gorge is easier to… Continue reading

Living on Borrowed Land
Why do mature redwood trees have trunks that rise two hundred feet before branches commence, live for centuries and have bark that’s a foot thick? Because they are adapted to fire. Why does the silver-green chaparral that covers California’s hills and mountains burn so easily? Because it’s supposed to. Why, other than its color, is… Continue reading

Geology vs. Weather
I love this: … and I hope the good (or evil, depending on your perspective) folks at Despair.com don’t mind my promoting their best t-shirt yet. (If it helps, I just ordered one.) You’ll notice that blogging isn’t in the diagram (though Despair does feature it in four other purchasable forms). I bring that up… Continue reading

Thinking past the I-I boundary
For the form of life we call business, we are at a boundary between eras. For biological forms of life, the most recent of these is the K-T boundary between the Mesozoic and the Cenozoic Eras. The Mezozoic Era ended when Earth was struck by an object that left a crater 110 miles wide and… Continue reading

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… Continue reading
