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 and now mostly obliterated by agriculture and the developing city of Portsmouth, Ohio. [1] [2]
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]
