Palm Canyon was occupied during the winter months, but they often moved to cooler Chino Canyon during the summer months. Numerous prominent and powerful Cahuilla leaders were from the area, including Cahuilla Lion ( Chief Juan Antonio).
They spoke Ivilyuat, which is a Uto-Aztecan language. Cahuilla Indians lived here in isolation from other cultures for hundreds of years prior to European contact.
The first humans to settle in the area were the Cahuilla people, who arrived 2,000 years ago.
