The Itasca Bison Kill Site is the oldest archaeological site within Itasca State Park. The site dates back to the Early Eastern Archaic period. The discovery took place in 1937 during the construction of the Wilderness Drive. It is located near the southwestern shore of Lake Itasca by Nicollet Creek. An initial finding of the remains of human made artifacts prompted the University of Minnesota to conduct an extensive excavation of the area in 1964 and 1965. Excavation of the area revealed a large of amount of bones from an extinct species of Bison hence the name of the site. Human tools, such as knives, spears and scrapers were discovered in the vicinity.[9]
