The Anasazi, Apache, Hualapai, Havasupai, Hohokam, Mogollon, Salado, Sinauga, and Tohono O'odham, Yavapai,  and Yuma Peoples lay the foundation for survival in the Desert Southwest and the mountains of what is now Arizona. The Hohokam created the Casa Grande (ancient ruins near Coolidge AZ.) They are probably some of the first inhabitants of the Phoenix Metro area. The Papago (Tohono O'odham) are believed to be direct descendants of the Hohokam.
