I was confused by the image too:

Having recently gotten into watching documentaries or youtube videos of accounts of mountaineering expeditions it's amazing how lazy content creators, film makers and journalists can be when choosing what images or videos to show. You'll get something about climbing a mountain in the Andes and keep getting shown completely misleading pictures of Himalayan mountains, etc.

Darn AI agents, I guess they are still cheaper than interns.

I can also recommend: "The Earth: An Intimate History" by Richard Fortey

Second for John McPhee! Also Rising From the Plains.

References to his books should carry a warning - something to the effect of:

"may inspire circuitous road trips involving many stops dangerously examining road-cuts on busy interstate highways"

You sly dog.

And the speed at which it happens:

> 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.
