efforts by supernatural charms reminiscent of Great Basin antelope drives (pp. 214-215).

Nathaniel Wyeth evidently saw few Shoshone in his travels through Wyoming, and his journals do not add greatly to our understanding of the area. He traveled from the Snake to the Green River in June and July, 1832, via the Teton country and mentioned no Shoshone except for a small encampment near Bonneville's post on the upper Green River (Wyeth, 1899, pp. 203-205). However, he reports that a white trapper was attacked in July, 1833, on the lower Wind River by a party of fifteen Shoshone who had left Green River shortly before (p. 207), and, in 1834, he found himself among "too many Indians ... for comfort or safety" while near Hams Fork, Wyoming (p. 225).

The journals of Osborne Russell provide documentation of population movements in Wyoming during the years 1834-1840. Despite the decline of the fur trade during this period, the area was still turbulent. In November, 1834, a party of trappers was reported as having arrived at Fort Hall, Nathaniel Wyeth's new post, after having been routed by the Blackfoot on Hams Fork (Russell, 1955, p. 8). The spring of 1835 took Russell to the west side of Bear Lake, where he found "about 300 lodges of Snake Indians" (p. 11) and in July of that year he encountered a small party of Shoshone hunting mountain sheep in Jackson Hole (p. 23). The lure of trade still attracted many other Indian groups into the Green River country during and preceding the time of the summer rendezvous. Russell reported an encampment of 400 lodges of Shoshone and Bannock and 100 of Flathead and Nez Percé on the Bear River above the mouth of Smith's Fork on May 9, 1836. The congregation was so large that it was forced to fragment in order to seek subsistence; all planned to return on July 1, when supplies were expected (p. 41). Russell spent the winter of 1840-41 with some 20 lodges of Shoshone in Cache Valley, Utah, and near Great Salt Lake (p. 112).
