Episode #049: Subglacial Floods in Southern British Columbia

Summary

In this episode, Randall Carlson and his crew delve into the geological impacts of megafloods, specifically focusing on the Missoula Floods and the subsequent effects these had on the landscape. They explore the timeline of these events and propose a re-evaluation of the accepted chronology associated with these catastrophic drainings. By linking these phenomena to a broader continental catastrophe, Carlson raises key questions about our understanding of Earth's past.

Key takeaways

• 1Missoula Floods linked to significant geological shifts
• 2Exploration of proglacial lakes and catastrophic drainings
• 3Examination of subglacial floods in south-central British Columbia
• 4Discussion on the Younger Dryas Impact Hypothesis
• 5Reevaluation of geological timelines surrounding megaflood events

That's AncientNutrition.com code protein. This is Cosmographia, the Randall Carlson Podcast. And we are back, ladies and gentlemen. This is Cosmographia, the Randall Carlson Podcast. We welcome all of you here, and we are joined, as usual, by the usual suspects. We got Silent Mike over there in his corner. How you doing, bud? Brad, what's going on with you this week, sir? I'm back. I am back in black. Back in black. Oh, yeah. Yeah. Got the Cosmo shirt on. Oh, the vintage Cosmo shirt. Old school Cosmographia. And Randall. Yeah. Randall, how are you doing, sir? Doing okay there, Russ. That's good. Yes, sir. So we were, before the show, we were looking at terms and talking about new papers you've got, some of the new research you're doing, but where are we going for today? What's the topic? Well, I thought we'd pick up the Drumlin theme. Yeah. Because we started into that so effectively with Jerome's guest shot. So I think we should continue with that a little bit and tie that back into some of the ideas associated with it, and the implications and the formation of some of the meltwater streams and lakes and things that we've been talking about, because all of those things are key to deciphering this whole process of how you transition from a full-blown glacial age into a full-blown interglacial age over a matter of, you know, 5,000, 6,000 years. Yeah, all right. And I think, I mean, we have talked about this several times, but a big key for me in Jerome's presentation was, you know, he was just like, this isn't a settled question, the Drumlins. This is a big problem. There's too much water, but we can't explain it with the glacier action. ...
