Episode #071: Pressure - Enemy of Glacial Ice Dams / Outburst Floods

Summary

In this episode, Randall Carlson challenges the outdated Ice Dam model that attributes the formation of the Channeled Scablands to Lake Missoula. He presents evidence that suggests other significant meltwater sources existed during the Ice Age Megafloods. The podcast emphasizes the importance of re-evaluating geological models based on new data and insights from various scientific studies.

Key takeaways

• 1Lake Missoula has been traditionally credited as the primary water source for the Channeled Scablands.
• 2Randall Carlson cites studies from the past century that dispute the feasibility of retaining a 600 cubic-mile, 2100 feet-deep lake under a temperate glacier.
• 3Evidence from the breaching of the Hubbard Glacier in Alaska serves as a parallel to the processes that may have occurred during the Ice Age Megafloods.
• 4Carlson hints at more detailed breakdowns of the ice dam model in future episodes.
