Maine Geology: We Learn About Maine's Geological History & What Gems, Minerals and Fossils Are Here

This show is part of our ongoing coverage of topics relating to Maine's bicentennial.

What is the geologic makeup and history of Maine? We find out what geologists know--and how they learn--about Maine's bedrock formations and how periods of erosion, mountain-building,  metamorphism and other activity have led to what we have today. A combination of rock types distinguishes our state, from half a billion years ago until today. We will also hear about the new Mineral & Gem Museum—what they feature, and what gems and minerals are unique to Maine.
