Explanation:

Hohokam culture, prehistoric North American Indians who lived approximately from 200 to 1400 CE in the semiarid region of present-day central and southern Arizona, largely along the Gila and Salt rivers. The term Hohokam is said to be Pima for “those who have vanished.” The culture is customarily divided into four developmental periods: Pioneer (200–775 CE), Colonial (775–975), Sedentary (975–1150), and Classic (from approximately 1150 to sometime between 1350 and 1450).
