Teton Valley was originally known as Pierre's Hole. Rich in beaver, it was a favorite stamping ground for British and American fur traders and trappers between 1819 and 1840. “Old Pierre” Tevanitagon, an Iroquois Indian fur trapper of the Hudson Bay Company, gave his name to this beaver-rich valley. Pierre's Hole was the scene of the annual rendezvous of mountain men and suppliers, “The Great Rocky Mountain Fair,” in 1832. That wild party ended in a free-for-all battle with the Gros Ventre Indians, which the trappers and their Indian friends won. The valley was permanently settled in 1882.
