The Only Prehistoric Carvings in Michigan: The Petroglyphs
Ever been here? I’m hoping to get here sometime this year and see these for myself.
The Sanilac Petroglyphs Historic State Park near Cass City in the Michigan Thumb contains one of the coolest, most historic things in the entire state.
These petroglyphs are carvings made around 1,000 years ago by Native Americans...the ONLY known (or should we say, 'found') carvings to be made by Native Americans in Michigan. These carvings were discovered in 1881 in the aftermath of the infamous Michigan Thumb Fire of September 5, 1881, when a raging fire killed 282 people and destroyed over one million acres of Michigan land.

By pure luck, and accident, the fire revealed these hidden carvings that were shielded from view by trees, weeds, bushes and other types of foliage. These images are carved into a large rock 40 feet by 15 feet wide, most images being man, animals, and other carvings that are unknown and indescribable.
Deemed the only prehistoric carvings in our state, the petroglyphs can be viewed by the public only by calling the Sanilac Petroglyphs State Historic Park to get access approved; the images are eroding with time and visitations have purposely been limited.
Located at 8251 Germania Rd, Cass City.
