Prehistory
The term Patayan is used by archaeologists to describe the prehistoric Native American cultures who inhabited parts of modern day Arizona, California and Baja California. These areas included territory near the Colorado River Valley, the nearby uplands, and north to the vicinity of the Grand Canyon. The prehistoric people may have been ancestral to the Quechan. They practiced floodplain agriculture where possible, but relied heavily on hunting and gathering. Subgroups include the River Yuman, Delta–Californian, and Upland Yuman ("Pai").
