The Cosmic Tusk Podcast brings together George Howard and Randall Carlson for a wide-ranging conversation that moves from the megaflood geology of the Canadian Shield to the Younger Dryas boundary, through Monument Valley and the Colorado Plateau, and finally to Plato, Ignatius Donnelly, and what the original text of Timaeus and Critias actually says about Atlantis.

The geological thread runs through the whole episode. Randall makes the case that Lake Agassi formed not gradually but near-instantaneously, as the direct byproduct of multiple cosmic impacts over the Laurentide Ice Sheet, and walks through the Lake Nipigon basin as a candidate impact site with erosional signatures consistent with the Channeled Scablands. He then turns to Monument Valley, arguing that the buttes, mesas, and slot canyons of the Colorado Plateau bear the fingerprints of catastrophic water flows on a scale nobody in mainstream geology has yet addressed directly. The pattern he keeps returning to is the same one that took decades to accept in Washington State: the landscape cannot be explained one drop at a time.

The Atlantis section closes the episode. Randall is careful about what he is and is not claiming. He has read Plato in the original Greek, and his position is that the geological dismissal of Atlantis published in 1977 relied on plate tectonics to rule out a sunken Atlantic landmass, while openly acknowledging that less than a fraction of a percent of the ocean floor had been explored at the time. The book declared the case closed. The ocean had barely been opened.
