The Bannocks (also Bannacks)— This name is derived from the Shoshoni word “bamp,” which means “hair,” and “nack,” which signifies “a backward motion.” It is also said that these Indians made cakes from acorn flour, pulverized grasshoppers, and currant jelly which so resembled the Scotch bannock cake in shape and flavor that some Scotch trapper applied this name to the tribe. There were approximately two thousand Bannocks in 1810, and they claimed the country southwest of Yellowstone. It was this tribe which made a deep trail across Yellowstone in going to and returning from their buffalo hunts. Bannocks were tall, straight, athletic people, possessed of more physical courage than most Indians. In a defensive way they were the most warlike of all Indians. The Shoshoni or Snake Indians— This tribe of natives lived in the upper Snake River Valley. According to Alexander Ross, the Snake Indians were so named because of their characteristic quick concealment of themselves when discovered. “They glide with the subtility of the serpent.” However, Indians interpreted the word “Shoshoni” as meaning “inland.”[71] Father DeSmet stated: “They are called Snakes because in their poverty they are reduced like reptiles to the condition of digging in the ground and seeking nourishment from roots.”[72] They lived in peace with the Flatheads and Nez Percés in the north and were at war with the Blackfeet, Crows, Bannocks, and Utahs. The Snakes were dependable participants in the trappers’ rendezvous so often held in the Green River Valley in the second quarter of the nineteenth century. TyGee was a leading chief during much of the nineteenth century. The Targhee Forest was named after this Snake chieftain. They were a short, very dark, heavy-set people, with small feet and hands but large chests and shoulders. Their disposition was quite peaceful and friendly toward other people, although they were very suspicious. They were excellent horsemen and good fighters when aroused. The whole nation consisted of about a thousand, but it was broken into bands, some of which were vital and murderous while others, such as the “Diggers,” were degraded and impoverished. Their great and constant occupation was to obtain food, and they were disposed to eat almost anything. [Illustration: Photo by W. H. Jackson _Family of Sheepeater Indians_] Tukuarikas or Sheepeater Indians— “Tuku” means “mountain sheep” and “arika,” “eat,” or “Sheepeater.” They were a slender, wiry people who possessed neither ponies nor firearms but used bows and arrows effectively. They wore furs and skins and lived among the rocks in the Gardner River canyon in Yellowstone and in the Salmon River Mountains of central Idaho. There were some two hundred Indians in the Yellowstone tribe. Their main support was from game and fish. These Indians did not possess any distinctive culture of their own, but, hermit-like, they seemed concerned only to carry on by themselves until further notice.
