Episode #090: Randall Carlson

We have a fantastic discussion with the one and only Randall Carlson about vulcanism, ancient mysteries, extinction events, the Younger Dryas, the Missoula Flood, Drumlins, Carolina Bays, the Great Chicago Fire, and much more!

We also discuss the upcoming Contact at the Cabin event with Randall and the guys from Grimerica in late May, which we will be attending, to go on field trips to sites of geological and archaeological interest.
