Note 44 — OREGON EXPEDITION

Pierre's Hole, known more recently as Teton Basin, is a grassy valley trending northwest and southeast, thirty miles long, and from five to fifteen wide, in eastern Idaho, just across the Wyoming border. Pierre (or Teton) River flows through it gathering affluents on the way. The valley was a well-known rendezvous, taking its name from Pierre, an Iroquois employé of the Hudson's Bay Company, who was here murdered by the Blackfeet. The Astorian overland expedition passed through this valley both going and returning (1811, 1812). The most notable event in its history was the battle which Wyeth recounts. It was not on the regular Oregon trail; see Townsend's Narrative, post.—Ed.
