Prehistoric Archaeology at 120′: Investigating 9,000 Year Old Hunting Sites Beneath Lake Huron

9,000 years ago, water levels in Lake Huron were much lower, exposing a dry land corridor where prehistoric peoples lived and herds of caribou migrated. Evidence of caribou hunting is found in archaeological sites 120 feet below the modern lake and have been investigated by the University of Michigan since 2009. These sites have been studied using sonar, ROVs, AUVs, and scuba divers and have revealed evidence of a subarctic Ice Age environment and culture during a critical time in Great Lakes prehistory.
