Folsom site or Wild Horse Arroyo, designated by the Smithsonian trinomial 29CX1, is a major archaeological site about 8 miles (13 km) west of Folsom, New Mexico. It is the type site for the Folsom tradition, a Paleo-Indian cultural sequence dating to between 11000 BC and 10000 BC. The Folsom site was excavated in 1926 and found to have been a marsh-side kill site or camp where 32 bison had been killed using distinctive tools, known as Folsom points. This site is significant because it was the first time that artifacts indisputably made by humans were found directly associated with faunal remains from an extinct form of bison from the Late Pleistocene. The information culled from this site was the first of a set of discoveries that would allow archaeologists to revise their estimations for the time of arrival of Native Americans on the North American continent.
