Episode #048: Meandering Meltwater Musings and Lake Agassiz
6October 15, 2020
Summary
The podcast explores the fascinating geological features known as drumlins, created by massive ice sheet meltwater. Host Randall Carlson and guest Jerome Lesemann discuss the historical significance of Glacial Lake Agassiz and the implications of megafloods on the landscape. They highlight how these features challenge conventional gradualist geological theories.
Key Takeaways
- 1Jerome Lesemann discusses the formation and importance of drumlins.
- 2Glacial Lake Agassiz is a focal point for understanding megaflood dynamics.
- 3Features like relict flood channels and 'misfit' rivers question the Uniformitarian model of geology.
- 4The Palouse Hills in Washington serve as an analogy for studying crescentic forms mentioned by Lesemann.
