Originally, the Portsmouth Earthworks consisted of three sections extending over twenty miles of the Ohio River valley, crossing from Ohio to Kentucky in several places.

The Old Fort Earthworks consist of several sites, including the Old Fort Earthworks (15Gp1), Mays Mound (15Gp16), Hicks Mound (15Gp265), Stephenson Mound (15Lw139), and several other unnamed mounds and enclosures. It is also the location of Lower Shawneetown, a protohistoric/historic Fort Ancient and Shawnee settlement and colonial trading post which are all part of the Lower Shawneetown Archeological District,[4] along with the Thompson and Hansen Sites

Also known as the Biggs Site (15Gp8), Group C was a large series of concentric circles surrounding a central cone mound, believed to have been built by the Adena culture. This section of the earthworks is located in Greenup County, Kentucky several miles to the east of South Shore, but connected to Group B by a causeway.
