In Liberty, the missionary group waited for the rest of their travel party, a group of fur traders with whom they would travel as far as the continental divide. After some logistical complications, on May 25 they joined the Rocky Mountain Fur Company caravan led by mountain men Milton Sublette and Thomas Fitzpatrick.Nunis, Doyce B. Jr., Milton G. Sublette, featured in Trappers of the Far West, Leroy R. Hafen, editor., 1972, Arthur H. Clark Company, reprint University of Nebraska Press, October 1983. The fur traders had seven wagons, each pulled by six mules. An additional cart drawn by two mules carried Sublette, who had lost a leg a year earlier and walked on a "cork" leg made by a friend. The combined group arrived at the fur-trader's rendezvous on July 6. Eliza and Narcissa were the first Euro-American women to make this overland trip.
