Serpent Mound Location and the Friends Organization: Clarifying the Facts

There's a common misconception about the location of Serpent Mound and its associated organization. Let's set the record straight on this important Ohio archaeological site.

Actual Location of Serpent Mound

Serpent Mound is located in Adams County, Ohio—not in Peebles, Ohio as sometimes believed. The precise address is:

Serpent Mound State Memorial
3850 State Route 73
Peebles, OH 45660

Note: While the mailing address uses "Peebles," the site itself is in Adams County, approximately 5 miles northwest of the village of Peebles.
