The Geology of Mount Desert Island
A Visitor's Guide to the Geology of Acadia National Park
Two colored geologic maps of the island are associated with this guide. One, the bedrock geologic map (pdf format), shows the type and distribution of bedrock on the island as if all the overlying vegetation, soil, sand, and gravel were scraped off. The second, the surficial geologic map (pdf format), shows the type and distribution of materials deposited during and immediately after glaciation, as well as materials formed in recent times.
