<P> In 1823 a St. Louis merchant named William Henry Ashley ( started the rendezvous system ) led a party up the Sweetwater to its source , rediscovered the pass ( look back to previous paragraph ) , and spent the summer in its vicinity trapping . He returned again in 1824 , this time going as far as Great Salt Lake and setting up a trading post there , which after three profitable years he sold to the Rocky Mountain Fur Company , headed by William Sublette , and David Jackson . </P>
