Serpent Mound
A 1,348-foot serpent undulates along a bluff above Ohio Brush Creek, its spiral tail, curves, oval head feature, nearby burial mounds, and unresolved chronology demanding slow, respectful observation.
Artwork inspired by Alice Schille
Serpent Mound is an effigy, not a burial mound, though burial mounds from different periods stand nearby. Excavations found no diagnostic objects inside the serpent itself, and radiocarbon samples have produced competing arguments for an Adena-period or Fort Ancient-period construction. The uncertainty is not failure: it demonstrates how archaeological claims are built, revised, and limited when sacred landscapes contain little datable material.
Walk the full path before seeking an overview. Its builders likely experienced the figure through movement rather than from above, and contemporary Native connections matter more than speculative claims about aliens or lost races. A restored observation tower may offer a broad view when open, but it requires narrow stairs. Entry closes at 4 p.m. even though the grounds remain open until 5.

Good to know
Access is permitted only during posted hours, and the gate closes to arriving vehicles at 4 p.m. The tower requires narrow stairs and may close for maintenance; the entire effigy cannot be seen from one ground-level point.
