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.^[1][2]

Description

The site was surveyed and mapped by E. G. Squier in 1847 for inclusion in the seminal archaeological and anthrolopological work Ancient Monuments of the Mississippi Valley. They described the earthwork as being a causewayed embankment 5 feet (1.5 m) high by 30 feet (9.1 m) wide encircling a ditch 6 feet (1.8 m) deep and 25 feet (7.6 m) across. They encircled an area 90 feet (27 m) in diameter. In the center of the ditch was a conical tumulus 8 feet (2.4 m) high and 40 feet (12 m) in diameter.^[3]
