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 Percé, 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 Percé 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.
In November, 1832, it was reported that "a village of Snakes and Ponacks amounting to about two hundred lodges on Gordiez [Big Lost] River" was attacked by a party of Blackfoot (ibid., pp. 185-186). The "Snakes" drove them off, but the "Horn Chief" was killed. The Horn Chief was reported on the Bear River in 1830 (ibid., pp. 71-73). This group may have been the same one mentioned a month later as being in winter camp on the Portneuf River (ibid., p. 188). Another Bannock camp was found in December, 1832, on the Blackfoot River. Ferris wrote (ibid., pp. 189-190):
I visited their village on the 20th and found these miserable wretches to the number of eighty or one hundred families, half-naked, and without lodges, except in one or two instances. They had formed, however, little huts of sage roots, which were yet so open and ill calculated to shield them from the extreme cold, that I could not conceive how they were able to endure such severe exposure.
Ferris' description does not seem typical of the Plainslike Bannock Indians. There are two possible explanations: these Bannock had been attacked by hostiles and had lost their possessions; or they had recently moved westward from Oregon. The latter possibility cannot be ruled out, for the Bannock and the Northern Paiute were in contact during the salmon season and the Oregon people drifted over to join their colinguists on the upper Snake River until much later in the century.
The presence of the Horn Chief on the Big Lost River in Idaho and the Bear River in Utah bespeaks the fact that the residents of eastern Idaho entered the northern Utah region quite as frequently as did the Shoshone of western Wyoming. Zenas Leonard reported meeting Bannock Indians some four days' travel west of the Green River. Depending on their speed, the trappers may have been in southern Idaho or some part of northern Utah. Leonard wrote of the Bannock (1934, p. 105):
On the fourth day of our Journey we arrived at the huts of some Bawnack Indians. These Indians appear to live very poor and in the most forlorn condition. They generally make but one visit to the buffaloe country during the year, where they remain until they jerk as much meat as their females can lug home on their backs. They then quit the mountains and return to the plains where they subsist on fish and small game the remainder of the year. They keep no horses and are always easy prey for other Indians provided with guns and horses.
It would be difficult to imagine a people without horses traveling across the Continental Divide for buffalo, and it must be assumed that the near-by herds that then existed were used.
