The fur trade brought white trappers to the area. In 1812 Robert Stuart, returning from Astoria, Oregon, heard stories from white men on the Snake River of a river to the south; he was persuaded to take a look at what he later called Miller's River, named after his guide, Joseph Miller. William Sublette led a party in 1824 from the Green River to Soda Springs, the Bear River's northernmost point. So colorful were the stories of the Bear River that the trappers' rendezvous of 1825 and 1827 were held here. Jedediah Smith attended the 1827 rendezvous after his ill-fated California trip. Peter Skene Ogden locally directed the Hudson's Bay Company policy to rid the region of furs in order to discourage American traders and settlers. Other famous trappers who visited the Bear River include B.L.E. Bonneville, Zenos Leonard, Black Harris, and Osborn Russell. Missionaries who visited the river included Jason and Daniel Lee as well as Father Jean Paul De Smet. John Charles Fremont explored the area in 1843 and his report helped prepare the Mormons for their new life in the West.
