Summary

This episode explores the geological implications of the Meteor Crater impact in Arizona, referencing a pivotal 1997 paper by David Kring. The discussion extends to potential impacts from past cosmic events, with a focus on the Younger Dryas and its controversial theories. Field observations from previous trips highlight the dynamic erosional processes that may have shaped the landscapes we see today.

That's AncientNutrition.com code protein. This is Cosmographia, the Randall Carlson Podcast. And welcome back, ladies and gentlemen, to Cosmographia, the Randall Carlson Podcast. We are joined by all the usual suspects this time. Mike is back with us. How you doing, Mike? Hey, buddy. Gives us the wave. The normal guy wave. Hi there, guys. Brad, how you doing? I'm good, man.

You know, we kind of just went through a sightseeing portfolio last week. We didn't really get into discussion too deep about the forces at work. So, that will be a continuing theme. But, yeah, there was a couple more things. I mean, you had a really beautiful panorama of Meteor Crater, Kyle. And I would like to say, though, that after spending that week on the road and seeing all that stuff, seeing Valley of the Gods, the Mokey Dugway, Meteor Crater, seeing Rock Art Canyon and stuff, man, I was so out there in the cosmos that being back here, being on a podcast, seeing Normal Guy again, it's just helping me to kind of come back to Earth. So, grounded. Thank you, Mike, for that. You're welcome. ...
