Fort Hall (Bannock County, Idaho)

Bannock County · Idaho · Fur Trade Era / Oregon Trail Migration

Quick BriefBuilt in 1834 by Boston inventor Nathaniel Jarvis Wyeth on the Snake River in present-day Bannock County, southeastern Idaho, Fort Hall became the only American trading post in that remote region of the Oregon Country. Unable to compete with the Hudson's Bay Company, Wyeth sold the post in 1837. After the 1846 Oregon boundary settlement, Fort Hall developed as a critical emigrant station through the 1850s, with an estimated 270,000 travelers reaching it on their way west.

History & Significance

In July 1834, after his fur-trading partners refused his goods at the annual rendezvous, Boston entrepreneur Nathaniel Jarvis Wyeth redirected west toward the Snake River country with surplus inventory. He and his party traveled roughly 150 miles to the Snake near the mouth of the Portneuf River, where they constructed wooden storehouses and completed a palisade on July 31, 1834.

Wyeth named it after Henry Hall, a major investor. The Hudson's Bay Company, already entrenched in the Snake country, drove Wyeth's company from the region, and he sold Fort Hall to the HBC in 1837.

The company rebuilt it in adobe and enlarged it considerably, making it a center of the Rocky Mountain fur trade until about 1856. After U.S. acquisition of the Oregon Country in 1846, Fort Hall became the junction where the Oregon and California Trails diverged, serving as a critical supply station for overland emigrants through the 1850s.

A Snake River flood destroyed the original fort in 1863, and it was briefly rebuilt in 1864 as a stagecoach station before being abandoned. The original site was designated a National Historic Landmark in 1961.
