Morongo Band of Mission Indians
A nation today
Background
The Band's first reservation was 640 acres, established in 1865, and for more than a decade the land was known as the Malki Reservation before a presidential executive order of May 15, 1876 created the Morongo Indian Reservation. The reservation now spans nearly 40,000 acres of ridgelines, canyons and open space, with cattle still grazing the backcountry as they have for decades, and the Band says it was the first tribe in the nation authorized by the Federal Energy Regulatory Commission to own a participating transmission line, through Morongo Transmission LLC, which it credits with tripling the capacity of 48 miles of power line. Tribal Members elect a seven-member Tribal Council, and the Band is organized across 17 government departments. Its cultural heritage site publishes language learning under three of its own names, Cahuilla 'ÍVILLU'AT, Cupeño PÁ'ENEXILY and Serrano MAARRÊNGATWICH, all of which the Band places in the Uto-Aztecan family, and carries the statement Mu Chemqal, we are still here.

The Band's cultural heritage site offers learning pages for three languages, Cahuilla 'ÍVILLU'AT, Cupeño PÁ'ENEXILY and Serrano MAARRÊNGATWICH, and describes the work as keeping the languages alive for future generations. It classifies all three as Uto-Aztecan languages spoken within the western United States and Mexico.
