Exploring Ohio's Edge of Appalachia
Exploring Great Serpent Mound
Adams County's most famous landmark, Great Serpent Mound, can seem to be playing hard-to-get. On a ridge above Ohio Brush Creek, a 1,330-foot earthwork snake uncoils in grassy, dandelion-speckled loops.
The millennia-old Native American site lacks interpretative plaques, and the small museum holds irregular springtime hours, leaving many visitors to explore on their own. A viewing tower will give you the best overview of the site, generally considered the world's largest single effigy mound.
