The Ice Age in Maine and the Maine Ice Age Trail
February 8, 2020 @ 2:00 pm - 3:30 pm
Post-glacial history viewed from the bottom of Sargent Mountain Pond in Acadia National Park
Stephen A. Norton, Professor Emeritus in the School of Earth and Climate Sciences at the University of Maine will discuss the origin of ice ages (the rise and demise of ice sheets) and impacts on the local landscape from advancing and retreating ice, vertical motion of the land surface, and rising sea level. These processes are illustrated by sites along the Maine Ice Age Trail founded by Professor Harold Borns. The post-glacial evolution of our landscape will be reconstructed through the study of a 16,000 year-long sediment core (17 feet of sediment!) from Sargent Mountain Pond, Maine’s first lake, nearly at the top of Sargent Mountain in Acadia. The talk is divided into two parts: 35 minutes, a 10 minute break, and 35 minutes.
