Those Shoshone and Bannock who did not follow the buffalo party carried on the fall hunt in southeastern Idaho, northern Utah, and western Wyoming. The elk and deer hunted could best be taken by small groups, hence hunting parties were not large and communal techniques were not necessary. Also, since these animals were scattered throughout the region and did not travel in the huge herds characteristic of the buffalo, the population had to spread out accordingly. Somewhat larger groups gathered to hunt antelope, but these were temporary aggregations. The actual size of the fall hunting groups is uncertain. One informant said that each consisted of about fifteen tipis, while another said that groups of two to four tipis were common. These smaller camp groups were known as _nanogwa_. Their size was said to have made them more vulnerable to attack than the somewhat larger concentrations. Some locales were known to have a plentiful supply of certain game animals. Caribou County in southeastern Idaho was considered good for deer hunting, while Jackson Hole and Yellowstone Park were noted for elk. The arid highlands of southwestern Wyoming abounded in antelope. Of course, all of these areas contained other types of game, and wild vegetables could be obtained in all. The fall hunt began at the end of August or in early September when the game was growing fat. Some parties went from Camas Prairie to Jackson Hole and Yellowstone via Idaho Falls and the Snake River. The route used was much the same as that followed by U.S. Highway 26. One informant spoke of Targhee Pass and West Yellowstone, Idaho, as being a point of entry to and departure from the Yellowstone country. The Snake River Trail was more commonly used to enter Jackson and Yellowstone, although West Yellowstone seems to have been more frequently traveled on the homeward journey. The west slope of the Tetons, the area drained by Teton River, was used also by hunting parties. Other Bannock and Shoshone camp groups went southward through the Portneuf Valley and over to the Bear River at Soda Springs; they followed the Bear River until they bore eastward to Kemmerer, Wyoming. Most camps of the Idaho Indians remained on the west side of the Green River. The chief game of the area was the antelope herds which were found on affluents of the Green River, northeast of Kemmerer. The Idaho Shoshone and Bannock were joined in the antelope hunt by the Eastern Shoshone of Wyoming and by the Ute, some of whom crossed the Uinta Range in early autumn for this purpose. Whether all these people actually combined for communal hunts is uncertain. It is more probable that small groups from each population amalgamated. Another attraction of the Green River country was Fort Bridger, where many of the Indians went for trade.
