Serpent Mound

Serpent Mound This is the Official page for Serpent Mound State Memorial. Serpent Mound is the largest surviving example of a prehistoric effigy mound in the world.

Serpent Mound is an internationally known National Historic Landmark built by the Ancient American Indian cultures of Ohio. Stretching 1,348 feet over the ground, the beautifully preserved ancient earthwork depicts larger-than-life sinews of an immense serpent, with an intriguing oval shaped head. This earthen monument is anywhere from 1000-2000 years old, and the cultural identity of its American

Indian architects remains wrapped in mystery, as does the exact ceremonial purpose behind its creation. Time, however, has not dampened the earthwork’s artistic affect on those who gaze upon it. The Serpent continues to elicit humility, wonder, and awe – drawing tens of thousands of visitors a year from across the country and the world. In addition to the Serpent, the park preserves three burial mounds of the Adena and Fort Ancient Cultures, and ancient village sites.

It was a great pleasure to be able to hear from tribal partners at the Summer Solstice today. Chief Glenna Wallace (Eastern Shawnee Tribe of Oklahoma) and Chief Ben Barnes (Shawnee Tribe) spoke to visitors about the history of their tribes. We were lucky to catch this photo of Chief Wallace from the Solstice sunset.

As part of the days leading up to the Summer Solstice, we hosted a program on snakes of Ohio with Jenny Richards, naturalist at Shawnee State Park. We learned about venomous snakes in Ohio and how they are misunderstood. Although they should be appreciated from a distance, they are seldom harmful to humans and don't need to be feared.

Friday's guest speaker will be at 11 AM in the picnic shelter. Our speaker will be Dr. Kurt Shoemaker, professor of geology at Shawnee State University. Dr. Shoemaker will be delivering a program called "Setting the Stage for the Serpent: The Ice Age on the Appalachian Plateau" where we'll learn about the ancient rivers and lakes that shaped southern Ohio.

The wildlife are active right now at Serpent Mound State Memorial.
🚨This is a yearly PSA for site visitors.🚨
It's okay to admire the wildlife you may see while visiting, but please don't touch or move the wildlife.
We ask that you don't get in their space. You may take a brief look or picture from afar and then we ask you leave them be.
Female deer intentionally hide their newborn fawns in tall grass or brush. Because fawns are born mostly scentless and have spotted coats for camouflage, staying motionless is their best defense against predators. The mother is usually nearby foraging and will return periodically to nurse.
If you spot a baby deer bedding down in tall grass, follow these simple steps to ensure its safety.
Don't touch or move it - Human scent can cause a mother to reject her fawn, and handling them is highly stressful for the baby.
Back away quietly - Leave the area so the mother feels safe enough to return.
Keep pets away - keep dogs on a leash while visiting and please keep them away from our wildlife as well.
We ask that you let the staff know if you see an animal, and where they are, while on site so we can give a heads up for other visitors.

Thank you for helping us protect the wildlife that call Serpent Mound home. By giving animals the space they need and observing them respectfully from a distance, you help ensure a safe and healthy environment for both wildlife and visitors. We appreciate your cooperation and stewardship.
