The Santa Rosa Band of Cahuilla Indians is a federally recognized tribe of Cahuilla, originally known as Ivilluwenetem, and are one of four Mountain Cahuilla tribes. Members of the Santa Rosa Band are the direct descendants of three Cahuilla clans – the Guanche-pakiktem, Costai-kiktem and Sawish-pakiktem – who traditionally occupied the areas of Toro Peak, Coyote Canyon/Anza Borrego, Garner Valley, Pinion, and the present-day Santa Rosa Reservation. The tribe is governed by a General Council, composed of all tribal members 18 and older, and administrative functions are carried out by an elected Tribal Council.
The Santa Rosa Reservation is located in Riverside County, California, between Palm Springs and Anza, and occupies 11,630 acres of land on five non-contiguous parcels. The largest parcel is located in the area of Sew’ia, or New Santa Rosa (Vandeventer Flat), where residents of the reservation reside. The Reservation was established by Executive Order on December 29, 1891.
