Have you ever wondered about the horizontal lines on Mt. Sentinel and Mt Jumbo? Or you have may have heard of references to an enormous glacial lake that filled the Missoula valley and beyond? Get an illustrated overview of Glacial Lake Missoula and learn how to see the mark it made across our landscape.

Geologist Bruce Baty will discuss the origin of Glacial Lake Missoula, a lake the size of Lake Erie, that existed in Western Montana 12,000 years ago. The Lake filled and drained many times and left evidence of its existence across the landscape in Montana, Idaho, and Eastern Washington.  This program will also explore some of that evidence, which is quite visible to the knowledgeable observer.

After or before the lecture, spend time in our Glacial Lake Missoula exhibit featuring video footage, photographs, maps, and detailed information on local GLM features.

Instructor: Bruce Baty graduated from Bowling Green State University in 1967 with a major in Geology.  In September of 1967 he enrolled in a masters graduate program in Geology at the University of Montana.  While there, he taught some undergraduate geology lab courses and enjoyed the challenge of designing course work, tests, and working with students.  As a result of those experiences, Bruce graduated with a master’s degree in geology with a teaching endorsement in earth Science.  He taught Geology and Earth Science at Hellgate High School for the next thirty years, retiring from teaching in 2001.
