As has been mentioned, not all the Shoshone and Bannock went to Glenn's Ferry to take salmon; those who did went in small groups rather than in a body. Parties followed the Snake River down to Glenn's Ferry, where they fished with harpoons. The Fort Hall people apparently did not make fish weirs. The weirs were usually the work of the winter population of the salmon areas, but one informant stated that the Bannock shared in the catch. Some Bannock continued downstream past Glenn's Ferry and fished in the Bruneau River, while others went to the Boise and Weiser rivers. Trade was conducted with the Nez Perce in the Weiser Valley; informants did not believe that the Bannock or the Shoshone took part in the trade with the Columbia River tribes in the Grand Ronde Valley in northeastern Oregon. This trade was, however, before the memories of any of our informants (or of their fathers). At the conclusion of the spring salmon run, the scattered camp grounds of Fort Hall Shoshone and Bannock went to Camas Prairie, where they dug camas, yamp, and other roots and fattened their horses for the fall hunt. Roots could also be dug in other areas, like the Weiser Valley and the plains and foothills near Fort Hall, and some families did not go to Camas Prairie. In most years Camas Prairie served as the marshalling grounds for the annual buffalo hunt. On these occasions, Bannock and mounted Shoshone of the Fort Hall area joined forces. While it is possible that these groups combined also with the Lemhi Shoshone for the buffalo hunt, we could obtain no corroboration of this grouping from informants. Informants generally stated that the buffalo party was composed chiefly of Bannock and was led by the Bannock chief. While many Fort Hall Shoshone took part, most hunted elk, moose, and deer on the western side of the Continental Divide. Furthermore, some Bannock did not take part in the hunt and similarly hunted in Idaho and southwestern Wyoming.
