petroglyphs with school group

Join the Michigan Department of Natural Resources at a virtual public meeting 6-7 p.m.Thursday, Sept. 29, to learn about and share feedback on a new draft phase 2 general management plan for Sanilac Petroglyphs Historic State Park.

The DNR uses general management plans to define a long-range planning and management strategy that protects a state park’s resources while addressing recreation and education needs and opportunities.

The virtual meeting will begin with a review of the draft plan, proposed improvements and planning process, followed by an opportunity for people to share feedback and questions with DNR staff. Advance registration is required.

petroglyph carving

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.

The park, which also features a 1-mile interpretive hiking trail that crosses a branch of the Little Cass River, is popular with school groups, hikers and visitors interested in Michigan history and Native American cultures. The 240-acre park is managed jointly with the Saginaw Chippewa Indian Tribe of Michigan and the petroglyphs are among the 12 museums and historic sites preserved and interpreted by the DNR's Michigan History Center.
