The Teton River is a tributary of the Henrys Fork of the Snake River, approximately 60 mi (97 km) long, in southeastern Idaho in the United States. It drains an isolated valley along the west side of the Teton Range along the Idaho-Wyoming border at the eastern end of the Snake River Plain. Its location along the western flank of the Tetons provides the river with more rainfall than many other rivers of the region.
Description
It is formed near Driggs in Teton County, Idaho, near the Wyoming state line, by the convergence of several small creeks that descend from surrounding mountains. Several of the creeks, including Teton Creek and Darby Creek, descend from the from western flank of the Tetons. Trail Creek descends from the Targee National Forest in Idaho, meeting the other creeks from the south. The river flows north in a slow meandering course through a broad flat valley called the Teton Basin (formerly known as "Pierre's Hole"), flanked by the Teton Range to the east and the Big Hole Mountains to the west. Much of the rivers upper course in the Teton Basin is surrounded by extensive wetlands.
After emerging from the north end of the Teton Basin it enters the nearly inaccessible Teton Canyon, approximately 25 mi (40 km) long, along the Teton-Fremont county line. In the canyon it is joined by Bitch Creek from the east, then turns west. It joins the Henrys Fork west of Rexburg at the southwest end of a large inland delta region on the Henrys Fork, essentially merging with the delta from the east as one of its channels.
History
At the time of the arrival of the Europeans to the region in the 1820s, the area was inhabited by the Shoshone are various related tribes. The lushness of the Teton Basin provided for prime area for the fur trade, attracting many other tribes to region, including the Nez Perce, Flathead and the Gros Ventre. At the time, the basin was part of the disputed Oregon Country. The resulting friction between the trading groups led to recurring skirmishes in the basin. In 1832, a trade rendezvous gone awry resulted in a battle between the Gros Ventre and a party of white trappers, led by Willliam Sublette and aided by their Nez Perce and Flathead allies. In the brief but bloody battle at least twenty-six Gros Ventres were killed, including women and children, and perhaps a dozen whites and Flatheads. Sublette receives severe injuries and returned east to the United States for medical care.
The most famous modern incident along the river occurred on June 5, 1976 with collapse of the Teton Dam in Teton Canyon, killing 11 people in valley below.
