Sublette was the entrepreneur of the trio. It was Bill who handled the outfitting, the business contracts, the transportation of trade goods and furs. That the partnership was successful is indicated by their disposal of their interests to Bridger and his partners in 1830 for an overall sum involving some $16,000. Sublette and his partners were shrewd enough to anticipate the gradual dissolution of the fur trade, which influenced their desire to get out of the business. It was Sublette’s wagon caravan from St. Louis to the Popo Agie and return in 1830 that proved the overland trail could be used by wheeled vehicles, this was the caravan that pioneered the immigrants’ route to Oregon. Sublette later returned to the west as a trader, in partnership with Robert Campbell, and built Fort William (later Fort Laramie) in 1834. Sublette and Jackson first entered Jackson Hole in 1826, after the rendezvous of that year near the Great Salt Lake. They crossed the lower end of the valley on their way to Green River, while their new partner, Smith, was headed with another contingent of trappers southwest across the desert toward California. The system of trading at annual summer “rendezvous,” several of which have been previously mentioned, was inaugurated by Ashley in 1825. The rendezvous site of that year was on Henry’s Fork of the Green River. By such a method, more flexible than the previously used “fixed fort” system, the trappers assembled at a previously determined place, conveniently located for the widely separated trapper bands. The trader brought his goods to the site where furs were exchanged for the trade goods. It was a time of celebration, frolic, and general carousal for all concerned. The rendezvous site can be likened to the hub of a wheel, the trails followed by the trappers as they came in from the spring hunt and departed for the fall hunt were the spokes. Thus rendezvous sites were on the Green, Wind, Popo Agie Rivers, at the Bear and Great Salt Lakes, in Pierre’s Hole, and finally at Fort Bonneville. Jackson Hole was never a rendezvous site because of the difficulty of access for the traders over the high mountain passes surrounding the valley.
