Evidence suggests that the Native Americans of the Archaic Period may have camped frequently at the mouth of nearby Seneca Creek at the foot of the Rocks. The famous Great Indian Warpath, known locally as the "Seneca Trail", followed the Potomac River, allowing the Algonquian, Tuscarora, and Seneca nations to transit the area for purposes of trade and war. Excavation for the building of the present Seneca Rocks Visitor Center uncovered evidence of two villages, the more recent of which thrived about 600 years ago. About a dozen dwellings were found.
