Map of named Glacial Erratics of North America, Geological Society of America, 1945.

Glacial Erratics are large boulders whose composition doesn’t match the surounding terrain. Trying to understand their origins led to the theory of that vast ice sheets had once covered the northern North American and it was the movement of these glaciers which had transported the rocks great distances. The Wisconsin Glacial Period, the last severe ice-age, was at maximum extent 26,000-20,000 years ago.
