Episode #068: Problematic Lake Missoula - Ice Dam, Mega-ripples, Strandlines

Summary

Randall Carlson challenges the mainstream understanding of the Clark Fork Valley Ice Dam and Lake Missoula, arguing that evidence points to rapid flooding events rather than prolonged rainfall. He claims that the geological features indicate multiple drainage and refilling events, contrary to established theories. This discussion invites listeners to reevaluate the historical narratives surrounding Ice Age Floods.

Key takeaways

• 1Evidence suggests Lake Missoula was filled suddenly by flows from the north, not by a century of enhanced rainfall.
• 2Carlson identifies evenly-spaced remnant shorelines as key indicators of a static lake that drained and refilled over forty times.
• 3The presence of mega-scale current ripples contradicts expectations of increasing size over time.
• 4The broad valley would need to be perfectly sealed to retain a 2100-foot water depth, raising questions about the long-accepted models.
