"This important family occupied a large part of the great interior basin of the United States. Upon the north Shoshonean tribes extended far into Oregon, meeting Shahaptian territory on about the 44th parallel or along the Blue Mountains. Upon the northeast the eastern limits of the pristine habitat of the Shoshonean tribes are unknown. The narrative of Lewis and Clarke contains the explicit statement that the Shoshoni bands encountered upon the Jefferson River, whose summer home was upon the head waters of the Columbia, formerly lived within their own recollection in the plains to the east of the Rocky Mountains, whence they were driven to their mountain retreats by the Minnetaree (Atsina), who had obtained firearms. ... Later a division of the Bannock held the finest portion of Southwestern Montana, whence apparently they were being pushed westward across the mountains by Blackfeet. Upon the east the Tukuarika or Sheepeaters held the Yellowstone Park country, where they were bordered by the Siouan territory, while the Washaki occupied southwestern Wyoming. Nearly the entire mountainous part of Colorado was held by the several bands of the Ute, the eastern and southeastern parts of the State being held respectively by the Arapaho and Cheyenne (Algonquian), and the Kaiowe (Kiowan). To the southeast the Ute country included the northern drainage of the San Juan, extending farther east a short distance into New Mexico. The Comanche division of the family extended farther east than any other. ... Bourgemont found a Comanche tribe on the upper Kansas River in 1724. According to Pike the Comanche territory bordered the Kaiowe on the north, the former occupying the head waters of the Upper Red River, Arkansas and Rio Grande. How far to the southward Shoshonean tribes extended at this early period is not known, though the evidence tends to show that they raided far down into Texas, to the territory they have occupied in more recent years, viz., the extensive plains from the Rocky Mountains eastward into Indian Territory and Texas to about 97°. Upon the south Shoshonean territory was limited generally by the Colorado River ... while the Tusayan (Moki) had established their seven pueblos ... to the east of the Colorado Chiquito. In the southwest Shoshonean tribes had pushed across California, occupying a wide band of country to the Pacific." _J. W. Powell, Seventh Annual Report., Bureau of Ethnology, pages 109-110._ "The Pah Utes occupy the greater part of Nevada, and extend southward. ... The Pi Utes or Piutes inhabit Western Utah, from Oregon to New Mexico. ... The Gosh Utes [Gosuites] inhabit the country west of Great Salt Lake, and extend to the Pah Utes." _H. H.
