Pierre's Hole is a shallow valley in the western United States in eastern Idaho, just west of the Teton Range in neighboring Wyoming.

With an elevation over 6,000 feet (1,830 m) above sea level, it collects the headwaters of the Teton River, and was a strategic center of the fur trade of the northern Rocky Mountains.

In 1984, it was designated a historic place as the site of the infamous events in the Battle of Pierre's Hole (below), following the well-attended Rendezvous in July 1832.

Explorer and mountain man John Colter, a member of the earlier Lewis and Clark Expedition, asserted that he passed through the valley in 1808.

At the end of the 1832 rendezvous, an intense battle ensued between a group of Gros Ventre and the party of American trappers aided by their Nez Perce and Flathead allies.

Teton Basin, was later settled by Mormon farmers, who used the fertile but elevated valley to graze cattle and raise hay and other feed.

Representatives of eastern fur-trading companies would arrive with pack mules loaded with trade goods to meet the needs of the trappers for the upcoming year.

Jean Baptiste Charbonneau, son of Sacagawea ("Pomp or Pompey"), was also in attendance on behalf of the Rocky Mountain Fur Company and participated in the Battle described below.

[2] Other well-known mountain men at the summer meeting included Joe Meek, a veteran of 22 years, and his friend Milton Sublette, brother of William.

Presumed dead by his fellows, the injured Fitzpatrick managed to escape captivity and, with the aid of Iroquois "breed" trapper Antoine Godin and some Flathead allies, return to the rendezvous before the pack trains headed back toward the east.

Two men new to the mountains, Nathaniel Jarvis Wyeth of Cambridge, Massachusetts and explorer Captain Benjamin Bonneville (Irving, Chapter VI) made their first appearance at rendezvous that year.

Henry Fraeb and Milton Sublette, with a group of some 100 trappers, planned to head for an area north of the Salt Lake desert.

Antoine Godin and a Flathead Indian "breed" (i.e. a half-breed) companion, sometimes identified as Baptiste Dorian, rode forward, appearing to greet the chief.

The murder provoked an intense battle between the Gros Ventres, with an estimated 250 warriors, and the party of American trappers aided by their Nez Perce and Flathead allies.

[2] Aid from the rendezvous camp, under the leadership of William Sublette, including additional Nez Perce and Flatheads, rushed to the scene of the impending battle.

[6] Thirty horses found nearby included some that had been previously stolen from Sublette's supply train and two that had been taken from Thomas Fitzpatrick during his earlier escape from the Blackfeet.
