Oct 2, 2020   While reviewing the events around the catastrophic drainings of Glacial Lake Agassiz, the ongoing question arises: What was the impulse of energy that initiated the domino procession of megafloods?  We continue to marvel at the oversized mid-continent spillways in the Dakotas, Minnesota, and Wisconsin – investigating multiple sites with the “advanced viewer” on the USGS National Map website, with particular focus on the underfit rivers, the massive potholes along the St. Croix (that we explored with Graham Hancock in 2014), and the discharges thru Lakes Nipigon and Superior. RC then broadens the connotations of “lake” to include more temporary impoundments of meltwater, which leads to a critical assessment of the current model of Lake Missoula and its Ice Dam. And in preparation for next episode’s special guest, Jerome Lesemann, we get an introduction to Canada’s extensive drumlin fields…  Kosmographia Ep046 The Randall Carlson Podcast with Brothers of the Serpent – Kyle and Russ, Normal Guy Mike and GCREX admin Bradley, from 09/07/20.
