Sanilac Petroglyphs State Historic Site: Exploring Ancient Stories Carved in Stone

The Sanilac Petroglyphs State Historic Site is in Michigan’s Thumb region, about a two-hour drive due north of Detroit. The park preserves the most extensive collection of Native American petroglyphs in Michigan. The rock art is called Ezhibiigaadek Asin, meaning “written on stone” in the native Anishinaabemowin language.

The highlight of the park is petroglyphs, of course, which are etched into a 1,000-square-foot sandstone outcrop. There are around 165 petroglyphs, which are believed to have been carved up to 1,400 years ago.

The mysterious figures, animals, and symbols have endured for hundreds of years, and were only discovered when a large forest fire ripped through the area in 1881. Some of the highlights you see during a visit include the Ebmodaakowet, an archer who shoots knowledge into the future, and Migizi Inini, the Eagle Man, who looks east towards the new day. Mishibizhew, the water panther, protects the waters of the Great Lakes.

There are a few interpretive signs around the covered petroglyph pavilion that help decode the carvings’ spiritual meanings, believed to represent teachings about harmony, nature, and balance.

Beyond the petroglyphs, the forested hiking paths, and the nearby Cass River, the peaceful atmosphere adds to the appeal, making it a rewarding stop for history enthusiasts and those looking for a quiet nature experience.

The petroglyphs pavilion is generally open to the public between Memorial Day and Labor Day. Check the park’s website for specific days before heading up.

The Sanilac Petroglyphs are remote, but worth a visit if you live nearby or are in the area. The historic site feels less like a tourist attraction and more like stepping into an ancient classroom— with lessons carved in stone.
