With the previously mentioned Paraguitsi, the Bannock Creek people were the only Idaho Shoshone who depended upon the pine nut for an important part of their winter's provisions. These nuts could be obtained in the Goose Creek and Grouse Creek Mountains in late September. One informant reported that, if the harvest failed, many people went into the mountains west of Wendover and Ibapah, Utah, for the gathering there. A family could gather sufficient pine nuts in the fall, it was claimed, to last it until March. The general round of migrations of the Bannock Creek people brought them into contact with the Shoshone of Nevada and with the small and scattered Shoshone groups of northern Utah, from whom they are almost indistinguishable. Buffalo hunting and common use of the Bear River region resulted in considerable interaction with the Eastern Shoshone, who also made use of this area in pre-reservation times. There was extensive intermarriage between the Eastern Shoshone and those of Bannock Creek and northern Utah, and one informant reports that their dialects were much alike. This affinity between the two groups finds further documentation in the belief of one of Steward's informants that the Bannock Creek people must have come from Wyoming (Steward, 1938, p. 217). FORT HALL BANNOCK AND SHOSHONE Above American Falls, the native population consisted of both Shoshone and Bannock Indians who were mounted and seasonally pursued the buffalo. Population aggregations were, in general, considerably larger than in any of the foregoing areas of Idaho. Ogden saw a "Snake" camp of 300 tents, 1,300 people and 3,000 horses on Little Lost River in November, 1827 (Ogden, 1910, p. 364), and Beckwourth claimed that he had met thousands of mounted and hostile Indians at the mouth of the Portneuf River in the spring of 1826 (Beckwourth, 1931, pp. 64-65). The journal of Warren Angus Ferris contains many references to the population in eastern Idaho in the period 1831-1833. The area evidently was frequently entered by warlike Blackfoot parties and by more peaceful groups of Flathead, Nez Perce, and Pend Oreille trappers and buffalo hunters (cf. Ferris, 1940, pp. 87, 146, 153-155, 185). Buffalo were still to be found and Ferris encountered large herds on the upper Snake River (ibid., p. 87); Nez Perce and Flathead Indians were seen on the divide between Birch Creek and the Lemhi River en route to hunt buffalo (ibid., p. 146). But the Indians most frequently encountered in the region were Bannock and Shoshone. On the Snake River plains near Three Buttes Ferris noted (p. 132): In the evening two hundred Indians passed our camp, on their way to the village, which was situated at the lower butte. They were Ponacks, as they are generally called by the hunters, or Po-nah-ke as they call themselves. They were generally mounted on poor jaded horses, and were illy clad.
