Roadside Geology of Maine

In this odd and spectacular North Country, contorted rocks reveal the strain of colliding continents, the heat of molton intrusions, and the weight of relentless glaciers. From the swarm of dikes along the rugged coast to the glacially polished granite of Mt. Katahdin, this book explores the fascinating geologic history of Maine's storied rocks. Detailed maps and road logs guide you through the woods to such hidden wonders as 100-mile-long eskers, frozen patterned ground, tourmaline-rich pegmetites, pillow basalts, and ice-age delta mud.
