That time a geologist in Moab showed me how the rock layers tell a different story than what textbooks say

He pointed out how a certain red sandstone layer in Arches National Park is actually upside down from a ancient quake, which got me wondering how many other 'established' timelines are just accepted without question. Has anyone else found physical evidence that challenges the official geological record?

I saw something similar in the Grand Canyon a few years back. A ranger pointed out how a basalt layer on top was actually older than the limestone below it in one spot. Turns out a massive landslide flipped a whole section of the cliff around. It really made me question how much of the standard timeline is just a best guess based on local conditions.

Kinda makes you wonder what else we've got backwards in life.
