Sanilac Petroglyphs Historic State Park, located near Cass City in Michigan's Thumb region, is the home of Michigan's largest known collection of early Native American teachings carved in stone. The carvings - called ezhibiigaadek asin, "written on stone," in the Anishinabe language - remain culturally significant to many Anishinabek.
Visitors will walk along a quarter-mile, accessible trail consisting of hard-packed limestone to a roofed enclosure that sits over the petroglyphs viewing area.
The park also features a mile-long, self-guided interpretive hiking trail loop that crosses a branch of the Little Cass River. Please note that this trail has roots and an uneven surface, and the trail can flood and may be muddy or impassable at times.
