Sanilac Petroglyphs Historic State Park (Phase 2)

The DNR is in the process of developing a new phase 2 general management plan for Sanilac Petroglyphs Historic State Park. Public and stakeholder input will be a critical part of the process.

The phase 2 general management plan will establish long-range action goals for the park and each of the management zones defined in the phase 1 plan.

A park's general management plan defines a long-range (10- to 20-year) planning and management strategy to protect and preserve the site’s natural and cultural resources and provide access to land- and water-based public recreation and educational opportunities.

About the park

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 240-acre park is jointly managed with the Saginaw Chippewa Indian Tribe and includes a 1-mile long hiking trail which crosses the north branch of the Little Cass River.

Public input

The DNR shared information and solicited public feedback on a new draft phase 2 general management plan for the park for the park at a virtual public meeting Thursday, Sept. 29. The virtual meeting began 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.
