About this map

The Tohono O'odham Indian Reservation landscape is defined by the significant rise of the Mesquite Mountains and the central prominence of Chupan Mountain. This desert terrain shows a distinct pattern of isolated water sources essential for survival in the arid environment, such as Vasquez Well and Stone Tank. These landmarks provided critical stopping points along the unimproved roads and pack trails that cross the desert floor between the high peaks.

The topography transitions into broad basins including Quijotoa Valley to the north and Kom Valley to the southeast. At the center of the sheet, Mamtotk Peak stands as a notable high point within the reservation boundaries. This 1990s representation of Pima County captures a largely undeveloped wilderness where cattle management is evidenced by several Corral sites, reflecting the enduring ranching practices on tribal lands.
