Fort Hall contracted with the Rocky Mountain Fur Company to accept trade for furs collected by their mountain men.  The fort decayed over the years after disuse and was not rediscovered until 1993. The real fort sits on Indian land so a replica of the archaeological site sits here.

The Rocky Mountain Fur Company, sometimes called Ashley's Hundred, was organized in St. Louis, Missouri in 1823 by General William H. Ashley and Major Andrew Henry (c. 1775-1832). They posted advertisements in St. Louis newspapers seeking "One Hundred enterprising young men . . . to ascend the river Missouri to its source, there to be employed for one, two, or three years." Among those hired were Jedediah Smith, the four Sublette brothers, including William and Milton, Jim Beckwourth, Thomas Fitzpatrick and David Edward Jackson, who in 1826, bought the Company and for the next seven years it continued to prosper. Other mountain men who worked for the Company were Jim Bridger, Joseph Meek, Robert Newell, George W. Ebbert, and Kit Carson.
