While limestone formations are famous at Mackinac, other geological wonders lie hidden underfoot. Today at Historic Mill Creek special programs highlight the grist mill which once ground grain into flour. Our millstones were hewn from “lost rocks,” boulders deposited by glaciers thousands of years ago. Learn what evidence of milling has been found here, how the process worked, and what grains were grown at the Straits of Mackinac. Also enjoy a lost rock scavenger hunt along the trails. #thisismackinac
Special programs at 11:00 a.m., 1:00 p.m., 3:00 p.m.
