About the Sanilac Petroglyphs Historic State Park

The Sanilac Petroglyphs Historic State Park can be found in Cass City — a small village located in Tuscola County — at 8251 Germania Road, right in the middle of Michigan’s thumb.

The park gets thousands of visitors each year and was established in 1971. Today, it’s co-managed by the Saginaw Chippewa Nation and Michigan’s DNR.

Hours, Admission, & Tours

While the state park itself is open 365 days per year, there is an enclosure that protects the historic carvings. That enclosure is only open between Memorial Day and Labor Day each summer.

Admission to the park is free, and a Michigan Recreation Passport is not required for entry. When you visit the park, you can take a guided tour to gain access to the enclosure and see the carvings for yourself.

It’s important to note that all guided tours are available on a first-come, first-served basis. We recommend that visitors allow a couple of hours to explore the park, including the petroglyphs, a self-guided walking trail, and so much more.

Seeing the Historic Petroglyphs Up Close

The park — called ezhibiigadek asin (written in stone) in Objibwe — contains Michigan’s largest collection of Native American petroglyphs, which date back to the pre-Columbian era.

It is unknown exactly when the Sanilac petroglyphs were created, but experts have estimated that they are anywhere from 300 to 1,400 years old.

They were discovered in 1881 when the Thumb Fire — also called the Huron Fire or Great Thumb Fire — killed about 300 people and burned over 1 million acres of land in less than one day.

The Petroglyphs

In all, there are 165 petroglyphs on a 1,000-square-foot sandstone outcrop. These fascinating depictions of cultural and religious Native American tribes that once lived in Michigan include lines, swirls, handprints, and even humans. Some of the most prominent carvings include:

  • Migizi Inini, the Eagle Man, is said to be flying over to make sure Native American traditions are being followed. He is looking to the east, said to symbolize the dawn of a new day.
  • Mishibizhew is said to be a protector of the Great Lakes.
  • The archer Ebmodaakowet is said to shoot knowledge into the future with his arrows.
  • Birds — including eagles, hawks, and owls — are said to symbolize wisdom and strength.
  • Shapes — including squares, zigzag lines, circles, and much more — don’t have a clear meaning but are thought to represent balance or harmony.
  • Snakes, which were drawn in coiled positions, are thought to symbolize healing or transformation because, in some Native American cultures, snakes were said to have medicinal properties.
  • Turtles are said to represent longevity or even fertility since they are drawn with their heads and legs extended.

The Park Trail

After you have learned more about the Native people who once called the Thumb region home and have seen the petroglyphs for yourself, you can embark on a mile-long hike on a trail that winds through the park’s forests.

Along this walking trail, you will be able to see what’s left of a 19th-century logging camp. In addition, there is a 110-year-old white pine tree that can be seen from the trail.

The trail circles a branch of the Little Cass River twice. While the trail is open to anyone and everyone who wishes to walk it, please note that the trail is uneven and can become impassible at times.

Sleeper State Park

Sleeper State Park is a beachfront park in Caseville where you can truly experience what it means to be at the tip of the Thumb. Since it is located on Saginaw Bay, you can actually watch the sunrise over Lake Huron in the east and catch pretty pink sunsets over the lake in the evening to the west.

Sunrises and sunsets are famous all over Michigan, but in most places, you are only going to get one or the other over the water. Here, you get the best of both worlds.

In addition to spending your day playing in the sand and cooling off in the crystal blue waters of this magnificent Great Lake, you can hike the trails in the park that lead you into the dune forests.

The introduction is highly recommended as it answers many questions people have regarding the petroglyphs before getting the interpretation.
