The state park, also known as ezhibiigadek asin (Ojibwe for "written on stone"),[3] consists of 240 acres (97 ha) in Greenleaf Township, Sanilac County, in Michigan's Thumb.

[5] Stone tools and pottery found in the park show that various tribal groups have occupied the area periodically throughout the last 8,000 years.

[3] The petroglyphs were thoroughly recorded in 1940 by Darrel J. Richards and Carl Holmquist of the Aboriginal Research Club of Detroit, who created drawings and castings of the carvings.

It has been walked upon and vandalized with graffiti over the years; someone, long ago prior to the 1920s, chipped out an entire symbol and the surrounding rock for a keepsake.

[2] The area is home to a wide variety of animals including: deer, turkey, ruffed grouse,[12] green heron, and belted kingfisher.

[14] On December 2, 2019, the Michigan Department of Natural Resources and the Saginaw Chippewa Nation signed a memorandum of understanding to co-manage the park.
