Hester Site (known by the two Smithsonian trinomials22MO569 and 22MO1011) is a major prehistoric archaeological site in Monroe County, Mississippi. It is a multicomponent site whose major occupation took place during the Archaic period with artifacts dating from 9000-8000 BCE, and other occupations during the Woodland and Mississippian periods.[3] The site is one of the largest Archaic sites in the southeastern United States, and its well-stratified nature was critical in providing for accurate relative dating of finds at other sites throughout the region. The site was declared a National Historic Landmark in 2001.[2]
