Nine thousand years ago, a dry land corridor connected northern Lower Michigan with Southern Ontario. This corridor provided a natural causeway from the semi-annual migration of caribou and an equally valuable terrain for Late Paleoindian and Early Archaic hunters seeking to exploit the herds.
Using survey techniques including side-scan sonar, multibeam sonar, autonomous underwater vehicles (AUVs), and remote operated vehicles (ROVs) – an international team of researchers led by the University of Michigan is searching for traces of ancient hunters beneath Lake Huron.
