The 500-Million-Year Geologic History of Casco Bay

June 24, 2021 @ 7:00 pm - 8:00 pm

A Maine’s First Ship Live Zoom Presentation

This presentation is a general overview of the nearly 500-million-year geologic history preserved in the bedrock of the Casco Bay region of mid-coastal Maine. Although the current coast of Maine is relatively tame in terms of dramatic geologic activity, this has not always been the case. Middlebury College Professor of Geology Dave West will provide insight into the dramatic history preserved in the geologic features of Casco Bay, including violent volcanic eruptions, massive earthquakes, and burial beneath over a mile of glacial ice. The spatial distribution of different rock types across the region, and how they relate to the present-day landscape, will also be discussed.

A North Carolina native, Dave obtained his master’s degree and Ph.D. in Geological Sciences from the University of Maine and has been conducting geological research in Maine for over 30 years.  He specializes in unraveling the bedrock geologic history of the northern Appalachians, with a particular interest in coastal Maine geology.  Prior to arriving at Middlebury in Vermont, Dave taught at Bowdoin College, Lafayette College in Pennsylvania, and Earlham College in Indiana.
