Despite the extent of the region in question, there were not many permanent, or winter-dwelling, inhabitants. Greater use was made of the natural products of this region by the more numerous Shoshone and Bannock, who wintered elsewhere, than by the small local population. The two chief resources were the extremely rich root grounds at Camas Prairie, in the vicinity of Fairfield, Idaho, and the fishing sites scattered between Glenn's Ferry and Shoshone Falls. Camas Prairie was used by the Bannock and, to varying degrees, by all the Shoshone of Idaho, as well as occasionally by other tribes, like the Flathead and the Nez Perce; the fisheries were used by the Bannock and all the Shoshone of the upper Snake River above Shoshone Falls, the limit of the salmon run. Some large stretches of territory were used very little, if at all. We were unable to obtain information on use or occupancy of the country north of the Snake River and south of the Sawtooths between Camas Prairie and Idaho Falls. This is extremely arid and infertile country, strewn with lava beds and containing little water. It was often traversed, but little subsistence was drawn from it. Also, scanty information was available on the territory west of the Bruneau River. One informant said that Silver City, Idaho, was within the limits of Paiute territory; according to other informants, the Bruneau River Valley was definitely within the Shoshone migratory range. It seems evident that southwest Idaho was not much used by either the Paiute or Shoshone, and, while both groups entered the area on occasion, boundaries could hardly have been narrowly defined. The population which wintered in the general area of the middle Snake River and drew year-round subsistence from the resources of the region was usually referred to by the term Taza agaidika, or "Summer Salmon Eaters." Other terms used were Yahandika, or "Groundhog Eaters," and Pia agaidika, or "Big Salmon Eaters." Steward reports the use of the terms Agaidueka and Yahandueka for the area (Steward, 1938, p. 165). One informant said that these were alternate terms which, however, did not change with the season or activities of the people designated. Lowie's Kuembedueka (Lowie, 1909, pp. 206-208) were not reported by our informants. Apparently, the names covered any and all people who wintered in the region and who were more or less permanent residents. The population included in these terms did not form a social or political group, nor did they unite for any collective purposes.
