(Sweetwater County, Wyo. - July 26, 2022)    With this year’s Fort Bridger Mountain Man Rendezvous at Fort Bridger in Uinta County scheduled for September 2 through September 5, the staff at the Sweetwater County Museum in Green River issued a reminder on Tuesday that the first Rendezvous was held in 1825 in what is now Sweetwater County.   

Organized by fur trading companies, Rendezvous were staged every year from 1825 to 1840 at different locations in Wyoming, Utah, and Idaho. Mountain men, trappers, and Native Americans gathered to sell their furs, trade for supplies, and celebrate.

That first rendezvous was staged on Henry’s Fork, three miles northeast of Burntfork and about 40 miles southwest of Green River. Mountain man James Beckwourth provided a description:

“ ...there was a general jubilee among all at the rendezvous, We constituted quite a little town, numbering at least eight hundred souls, of whom one half were women and children. There were some among us who had not seen any groceries, such as coffee, sugar,& c., for several months. The whisky went off as freely as water, even at the exorbitant price he [William Henry Ashley, co-owner of the Rocky Mountain Fur Company, for whom the Ashley National Forest is named] sold it for. All kinds of sports were indulged in with a heartiness that would astonish more civilized societies.”

The Museum’s gallery includes exhibits on Native Americans, mountain men, and the frontier-era fur trade. Hours are Tuesday through Saturday, 9:00 AM to 5:00 PM, and there is no charge for admission.
