There is evidence pointing to the emergence of the "Hopewell" culture in the Waverly area beginning about 300 BC. The namesake for the Hopewell is Captain M. C. Hopewell, the owner of the Ross County farmstead where artifacts leading to the discovery of the Hopewell's separate cultural identity were found. Both the Adena and the Hopewell are well known for their mounds, many of which still exist around southern Ohio, including several in Pike County, and just north of Waverly in Chillicothe, Ohio, where the Adena Mound is a registered historic structure. There is evidence of Hopewell in the area until about 600 AD. The cause of the demise of the Hopewell is unknown, and there is not much information available about the people immediately following them. Sometime after 1000 AD, the "Fort Ancient" people began to occupy southern Ohio, only to disappear in the 17th century, likely decimated by infectious diseases spread in epidemics from early European contact. Some scholars believe that the Fort Ancient people "were ancestors of the historic Shawnee people, or that, at the very least, the historic Shawnees absorbed remnants of these older peoples."
