The Biggs site (15Gp8), also known as the Portsmouth Earthworks Group D, is an Adena culture archaeological site located near South Shore in Greenup County, Kentucky. Biggs was originally a concentric circular embankment and ditch surrounding a central conical burial mound with a causeway crossing the ring and ditch. It was part of a larger complex, the Portsmouth Earthworks located across the Ohio River, now mostly obliterated by agriculture and the developing city of Portsmouth, Ohio.
