Discover Michigan's Only Known Prehistoric Rock Carvings!

April 10, 2014 - 7:00pm - 9:00pm
Cranbrook Institute of Science

Cranbrook examines the prehistoric on Thursday, April 10 at 7pm, when Institute of Science Anthropology Coordinator Cameron Wood, along with Stacy Tchorzynski and Dean Anderson, archeologists from the Michigan State Historic Preservation Office and the Department of Natural Resources, discuss Michigan’s only known prehistoric rock carvings--the Sanilac Petroglyphs. The carvings, located in the Thumb region, were discovered after a fire swept through the area in 1881 revealing the designs which were made about 300 to 1,000 years ago.

Following the free lecture, 30 paid attendees are invited to continue the conversation in the Institute’s collection vault with an examination of the original Sanilac Petroglyphs drawings and plaster casts made by Institute scientists in the 1940s.

Tickets are $30 per person for Cranbrook Members and $35 for the General Public. For reservations please contact Kim Larsen at 248 645.3319, or by email at
