John Colter accompanied Lewis and Clark through the Northwest in 1803-6, was the first white man to enter Teton Valley (Pierre’s Hole) in 1807, and discovered Teton Pass, Jackson Hole, and the wonders of Yellowstone Park, later called “Colter’s Hell.” He joined the Crow Indians and took part in the Battle of the Flats between the Crows and the Blackfeet. The next year he returned to this valley. A stone face found in Teton Valley in 1931 is inscribed: “John Coulter, 1808.” Coulter settled on a Missouri farm in 1810, where he died in November 1813, about 38 years of age.
