In January 1879, United States President Rutherford B. Hayes included Camelback Mountain as part of a one million acre (4,000 km2) reservation for the Salt River Pima and Maricopa American Indian tribes. Six months later, at the behest of Charles Poston, the Arizona Territorial Legislature reversed the decision in order to ensure the primacy of the 5000 non-Indian area residents as well as their continued access to Salt River water.
