Sanilac Petroglyphs Historic State Park
Sanilac Petroglyphs Historic State Park, Archaeological park with ancient petroglyphs in Greenleaf Township, Michigan, United States.
The state park contains a 1,000-square-foot sandstone outcrop featuring 165 distinct petroglyphs carved into the rock surface by Native American tribes.
Archaeological discoveries at the site indicate continuous human occupation spanning 8,000 years, with stone tools and pottery found throughout the park grounds.
The petroglyphs depict sacred figures from Great Lakes Native American tribes, including Ebmodaakowet the archer and Migizi Inini the Eagle Man.
The park maintains a 1.5-mile trail system through the Cass River floodplain forest, with wooden bridges crossing the water at two points.
In 2019, the Michigan Department of Natural Resources formed a partnership with the Saginaw Chippewa Nation to jointly manage this state park.
