#8Why does this article have a picture of the Maroon Bells? As opposed to something along Green River or, ideally, the 700m deep canyon being described?

#9Fascinating to think of entire mountain ranges moving up and down like the skin on a wobbly pudding.
> a cold, round anomaly about 200 km below the surface.
> By estimating how far the drip had fallen and calculating the speed of its descent, the researchers estimate that the drip broke off between 2 and 5 million years ago.
A few megayears later, the bit that broke off is still falling.
200km in 2m years, I make that in the ballpark of 0.1m per year - a bit less if it's > 2m years, and started below the surface.

#10For people interested in the subject generally I highly recommend John McPhee's anthology "Annals of the Former World." Actually I highly recommend everything John McPhee has written but this is a good start :).
