Agriculture in the prehistoric Southwest
After the Hohokam disappeared, Spanish explorers of the 16th century noted the use of canal irrigation in only two areas of the Southwest: eastern Sonora, primarily practiced by the Opata and Lower Pima, and among the Pueblos of northern New Mexico. Irrigation by the Opata and Pueblos had different objectives. In Sonora, with a long growing season, two crops of maize a year were grown in river valleys. The spring crop during the dry season was dependent upon irrigation; the summer and fall crop during the rainy season utilized irrigation to supplement rainfall. The necessity of irrigation probably required a high level of social organization. In New Mexico, with only one crop of maize per year possible, irrigation was supplemental and the lesser dependence on irrigation implies less social organization than in Sonora.
Tonto Apache
Typically hunter-gatherers, the Tonto Apache hunted (antelope, deer, birds, bush rats, etc.) and collected (agave, berries, wild plants, seeds). The women also cultivated watermelons, pumpkins, corn, later grain, etc. When stocks were running low and the stored food supplies were depleted, it was common that a respected woman (so-called 'woman chief' or elder) brought public attention to the plight. The woman asked the leaders of the "rancheria" to go on raids against other Indians and European-Americans to raid to acquire what was needed. The Western Apache raided over an area from the Colorado River in western Arizona, to the Zuni ("Nashtizhé"- 'black-dyed eyebrows') and Hopi ("Tseka kiné `"- 'people who dwell in stone houses') in the north, to the later Mexican states of Sonora, Chihuahua, Sinaloa and Durango in the far south.
