Laura and Mike did a special show today, during the Geographic Society of America.  We interviewed Nick Zentner, geologist at Central WA University in Ellensburg, and host and writer of the PBS series Nick on the Rocks as well as his YouTube geology channel which has 85 thousand plus subscribers.  Nick is in Spokane for the Geological Society of America’s Joint Cordilleran and Rocky Mountain Section meeting. We discussed geology in the Columbia Basin,  including some studies that indicate Spokane was once under an ice cap and a volcano in British Columbia erupted, melted the cap, and caused the first massive flood in the Columbia basin.  We did three station ID’s.
