Duane and Ruth Braun relate the fascinating story of the region’s formation, explaining how a slice of South America with Mount Desert Island bordering its southern side landed on the edge of North America to form Maine. Another piece of South America collided with this landing, causing Mount Desert Island to erupt violently in a ten mile wide volcanic caldera. The Island then underwent a long period of stream erosion culminating in a period of glacial erosion to form the present landscape. The exceptional scenery that resulted has attracted visitors from around the world. This book unlocks the many secrets of the formations, offering a deeper understanding of the land and its origins.
