Sanilac Petroglyphs Historic State Park
Michigan’s largest known collection of Indigenous rock carvings lies beneath a protective pavilion beside the Cass River, interpreted in partnership with the Saginaw Chippewa Indian Tribe.
Artwork inspired by Wa-bo-shi-she
The carvings are living cultural heritage rather than anonymous prehistoric decoration. Figures, tracks, beings, and lines carry teachings whose meanings are not exhausted by archaeological dating or outsider naming.
Visit during staffed seasonal hours when the pavilion is open, listen to Tribal interpretation, and keep hands, water, chalk, and tracing material away from the stone. The surrounding forest and river help explain why this exact outcrop mattered.
