A lecture: The phrase “underwater archaeology” conjures notions of shipwrecks, ships lost at sea, and the dramatic catastrophes that sank them; however, the archaeology underwater can also reveal details about ancient landscapes that contain a record of past human occupations. Many of these sites are on the earth’s continental shelves where vast stretches of shallow, coastal lands were exposed at the end of the last Ice Age. These once dry landscapes supported life for plants, animals, and humans for thousands of years. Learn about these ancient submerged sites, the role they play in the global archaeological record and what unique data they have about the past. The talk will provide a general overview and the focus on 9,000 year old submerged sites in the North American Great Lakes.
