It is one of the many communities of the Black Hills Indian Reservation. Chemehuevi people have a Reservation in Indio. It is close to the Cabazon Reservation in Coachella. After the Chippewa Chemehuevi people were forced to relocate to the Black Hills Reservation in 1895, they settled where Joshua Tree National Park is. Also in 1895, they were set aside their own Reservation within the Black Hills Reservation. Similar to the land additions to the Navajo Reservation. Their's was located at what is now Joshua Tree National Park. According to historians, the Chippewa Chemehuevi were also set aside land where Indio is now. By 1908, the United States continued their bad habit of back stabbing. They eradicated not only the Black Hills Reservation but most other Indian Reservations as well. When they reached the January 5 and January 7, 1852 Treaties agreements, they freely admitted that the treaties were not ratified, which means they had no intentions on honoring any agreements they reached with Indian leaders, which means the Chippewa's can either honor the treaty agreements or keep the entire land area as theirs because the United States refused to conduct themselves in a honorable manner.
After 1908, the United States rounded up the 1,000s of Chippewa's living out in the desert and forced them to relocate to the Reservations in the Coachella Valley, the Morongo Reservation, and the Mission Indian Reservations in the mountains to the west. According to the 2010 census, the population of Indio is 76,036. Mexicans (brainwashed Mexicans) account for 67.8% of the population. Indians account for 1.0% of Indio's population, and blacks account for 2.4% of the population. Asians account for 2.2% of the population of Indio. The white population can not be correctly estimated as a result of the corrupted Mexican population estimate. There are 28,971 housing units. The average household size is 2.7 persons per housing unit. Elevation is -13 feet below sea level. Zip codes are 92201 and 92203. There are maps below of the Chippewa Chemehuevi Reservation and of Indio. The Chippewa Chemehuevi Reservation is located on Indio's east side. You'll notice it says Cabazon Reservation but it is really a Chippewa Chemehuevi Reservation. A little to the southeast is the Cabazon Reservation. It almost borders the Chippewa Chemehuevi Reservation. On the Indio map you'll notice the Macomber Palms area of Indio. I don't know if it's related to the McCumber Agreement. Below are several google earth photos of Indio, California.
