Museum curator John O'Shea will speak about his archaeological discoveries in Lake Huron at a Tedx event in Rogers City, Michigan, on Friday, October 5, 2018.

John O’Shea, curator of Great Lakes Archaeology at the UMMAA, and Michigan artist Jack Dempsey will speak at the Presque Isle District Library tonight, October 5, as part of the first Tedx event in northeast Michigan.

O’Shea will talk about his work in Lake Huron, where he and his team have explored the underwater remains of caribou hunting sites about 9,000 years old. At that time, the region was above water, on a strip of land connecting Michigan to southern Ontario. This work is the basis for the 2015 book he co-edited with Elizabeth Sonnenburg and Ashley K. Lemke: Caribou Hunting in the Upper Great Lakes: Archaeological, Ethnographic, and Paleoenvironmental Perspectives.

Tickets are $10 and can be purchased online at rogerscitytheater.com. The event is from 7:30 to 10 p.m. Friday at the Rogers City Theater, 257 N. 3rd St., Rogers City.
