The Dyar site (9GE5) is an archaeological site in Greene County, Georgia, in the north central Piedmont physiographical region. The site covers an area of 2.5 hectares. It was inhabited almost continuously from 1100 to 1600 by a local variation of the Mississippian culture known as the South Appalachian Mississippian culture. Although submerged under Lake Oconee, the site is still important as one of the first explorations of a large Mississippian culture mound. The Dyar site is thought to have been one of the principal towns of the paramount chiefdom of Ocute, perhaps Cofaqui.
