Among the Shoshone of the Fort Hall region, leadership was more clearly a function of interaction with the whites. One man was said to have become chief "because he helped the whites." Two chiefs were reported, Aidamo and Aramun; the bands of both roamed through southeastern Idaho and into northern Utah. These Shoshone were called by the Bannock, "Winakwat," or "Wihinait" in Shoshone. The name evidently did not refer to a single band but designated all Shoshone-speaking people of the immediate area. I could find no confirmation of Hoebel's Elk Eaters, Groundhog Eaters, and Minnow Eaters, all of whom were said to live in the area roamed over by the various Fort Hall Shoshone and Bannock groups (Hoebel, 1938, pp. 410-413). In the Fort Hall area, as in the rest of Idaho, winter habitat supplies the only stable criterion for identifying the several groups or populations. The Bannock customarily wintered on the Snake River bottoms above Idaho Falls and at the mouth of Henry's Fork near Rexburg, Idaho. They also wintered downstream in the vicinity of the modern town of Blackfoot, Idaho; historical sources mention Bannock winter camps at the mouth of the Portneuf River. The Snake River--Henry's Fork sites were favored because of the abundance of the mule-tailed deer, which came into the bottomlands in the winter. Another source of subsistence in winter was cottontail rabbits, which were caught among the willows in the bottoms with a noose snare or by surrounding them and killing them with the bow and arrow. The main winter subsistence, and the food source that provided the margin of survival, was the dried meat of buffalo, elk, and deer taken in the fall hunts, supplemented by dried roots and berries. Food caches were maintained near camp, but they were generally resorted to only in the spring, when the dried food kept in the lodges was exhausted. The location of the cache was known only to the family that made it. Caches and their contents were considered private property. Dried roots, berries, and salmon were generally kept in the underground caches, but not meat. Bannock winter camps were spread out along the river; there was no central encampment. The population was predominantly Bannock, although many Shoshone lived among them either through in-marriage or by choice. Not all of the Bannock wintered on the Snake River. Those who crossed the divide for buffalo frequently did not return in time to cross the mountains before the snows blocked the high passes and so generally wintered in western Montana, not joining the rest until spring. The Wihinait, or Shoshone of the Fort Hall area, were said to have wintered apart from the Bannock on the Portneuf River. Winter camps ranged along the Portneuf between Pocatello and McCammon, and other places as far south as Malade City, Idaho, were sometimes occupied. Here, too, the population lived off stored food and whatever game could be taken.
