Answer:Many distinct Native American groups populated the southwest region of the current United States, starting in about 7000 BCE.
The Ancestral Pueblos—the Anasazi, Mogollon, and Hohokam—began farming in the region as early as 2000 BCE, producing an abundance of corn. Navajos and Apaches primarily hunted and gathered in the area.
These groups deserted the area around 1300 CE, probably due to crop failures; European colonists encountered people partially descended from the Ancestral Pueblos in the mid-1500s.Many different groups of Native Americans, with distinct cultures based on their resource allocation and climate, inhabited the western region of North America.
Hunting, gathering, and fishing supplied most of the food for indigenous people throughout the West, especially along the Columbia and Colorado Rivers.
Although hunting and gathering could be challenging and unpredictable, the bountiful West provided ample food and trading goods, which allowed Native Americans to establish sedentary villages.
