Cactus Hill is an archaeological site in southeastern Virginia, United States located on sand dunes above the Nottoway River about 45 miles south of Richmond. The site receives its name from the prickly pear cacti that can be found growing abundantly on-site in the sandy soil. Cactus Hill is one of the oldest archaeological sites in the Americas. If proved to have been inhabited 18,000 to 20,000 years ago, it provides evidence supporting the Solutrean hypothesis.^[1] The site has yielded multiple levels of prehistoric inhabitance with two discrete levels of early Paleoindian activity, but this evidence has not been accepted by mainstream archeologists.^[2]
