Bill Burgel, coming up from Portland, will talk about “Joseph T. Pardee and Glacial Lake Missoula.” Pardee was a USGS Field Geologist whose expertise was in Western Montana, where he was raised. He was the first to recognize, around 1910, the features of a vast, ancient Glacial Lake Missoula.
In the 1920s, working independently of Pardee, Harlan Bretz had determined from field evidence, that only an extraordinarily huge flood, or floods, could have carved out the Channeled Scablands in eastern Washington, and the dry coulees associated with them. But he did not know the source of the water. Pardee quipped that he “knew the source of Bretz’ water.” In 1925, he suggested to Bretz that the draining of a glacial lake could account for the magnitude of water flows needed to create the Scablands and coulees.
The program is free and open to the public.
