Palaeoindian and Archaic campsites at Flint Run, Virginia, with a long-exploited jasper quarry. Core fragments, flakes, and broken or preformed tools show a large flint knapping industry. Occupations began in Clovis times through the Archaic. Postholes in association with living floors dated to c 9000 BC raises the possibility of this being the site of the earliest house structures in America.
