The hunters ranged up the Boise and Payette valleys into the Sawtooth Mountains as far as the beginnings of the Salmon River watershed. Though the Salmon River country was entered, the hunting parties did not penetrate very far. A favored hunting territory was in the Stanley Basin, at the headwaters of the Salmon River and in the vicinity of the present-day village of Stanley. The kill of game was dried in the mountains and packed down to the winter quarters in the valleys of the Boise, Payette, and Weiser rivers. In general, it is difficult to define the social organization of the Boise-Weiser Shoshone. While Shoshone social organization is characteristically amorphous, some groups developed a closer integration owing to such factors as warfare and collective economic activities, which demanded leadership. But warfare was rare in this region, and hunting and root-and berry-collecting were essentially carried on by families. The building and operation of fish traps and the distribution of the catch undoubtedly called forth some leadership functions, but not on the band level. Also, the presence of other groups which fished the same streams during the appropriate seasons seems to argue against the consolidation of either the Boise or Weiser people into territorially delimited bands. It was impossible to elicit exact information from informants on the functions of leaders, and it can only be inferred that they probably served as intermediaries with the whites or were simply local men enjoying some prestige as dance directors or leaders of winter villages. The Shoshone of this area were poorer in horses than the buffalo hunters, but they did possess some. The valleys of the Boise, Payette, and Weiser evidently afforded adequate grazing for small herds, and the natives enjoyed a greater mobility than did their neighbors to the northeast and southeast. The resulting ease of communication would perhaps be conducive to band organization, but neither living informants nor historical sources offer any confirmation of this. That such sociopolitical groups did exist is suggested by mention of chiefs, but the groups did not have clearly defined territories which excluded other peoples, and they could only have been most loosely organized.
