Chasta Tribe. A tribe, probably Athapascan, residing on Siletz Reservation, Oregon, in 1867, with the Skoton and Umpqua, of which latter they were then said to have formed a part. The Chasta, Skoton, and Umpqua were distinct tribes which concluded a treaty Nov. 18, 1854. The Chasta were divided into the Kwilsieton and Nahelta, both residing on Rogue River. J. O. Dorsey thought these may have been identical with Kushetunne and Nakatkhetunne of the Tututunne. Kane, in 1859, located them near Umpqua River. In 1867 the Chasta, the Scoton, and the Umpqua together, at Siletz agency, numbered 49 males and 74 females, total 123.
They may be identical with the Chastacosta or form a part of the Takillua. They do not seem to have any connection with the Shasta, who did not extend down Rogue River below Table Rock, and who were generally bitterly at war with their Athapascan neighbors.
