On this bonus episode of CASCADE OF HISTORY, Feliks Banel digs into the archives for his 2017 conversation with Western Washington University Professor Emeritus (and geologist and author) Don Easterbrook. Easterbrook and his late colleague David Rahm studied Mount Baker - just minutes away via air from Bellingham - during the Whatcom County peak's period of increased volcanic activity in 1975 - five years before Mount St. Helens blew its top.

Easterbrook authored a book in 2016 called "Mount Baker Eruptions and Glaciations." He and Rahm are also co-authors of the essential 1970 text, "Landforms of Washington."
