The Tohono O’odham Reservation, the second largest in the United States, covers 4,400 square miles between Tucson and Ajo, stretching south to the Mexican border and north almost to the city of Casa Grande. To the south of Kitt Peak, the 7,730-foot Baboquivari Peak is considered sacred by the Tohono O’odham as the home of their deity, I’itoi ("elder brother"). Less than halfway between Tucson and Ajo, Sells—the tribal capital of the Tohono O’odham—is a good place to stop for gas or a soft drink. Much of the time there’s little to see or do in Sells, but in winter an annual rodeo and fair attract thousands of Native American visitors.
