Geology of MDI

Duane Braun , Ruth Braun

The Undercroft of St. John Episcopal Church, 315 Main Street, Southwest Harbor.
The geology of MDI will be explored from when MDI was part of the Gander terrane attached to another continent, through the development of MDI as a large volcano, to when glaciers sculpted the present landscape. Each session will start with a lecture and question period from 9:30 to 10:30 or so. Then from 10:30 to Noon or so, the class will take a field trip to examine the earth material and landform evidence for the geologic evolution of MDI. The lectures may be attended without going on field trips.
