Archaeologists dig at site believed to be from ancient bison

An archaeological team has started digging at a site believed to be the place where American Indians camped and hunted bison 12,000 years ago.

The Beacon Island site was uncovered after Lake Sakakawea began shrinking.

Fred Sellet, the field director of the archaeological team, said bone fragments of ancient bison already have been recovered, three days into the dig, along with stone tools.

The site is on federal land, and the dig is a cooperative effort involving the nonprofit PaleoCultural Research Group, the Army Corps of Engineers and the Three Affiliated Tribes.
