About this map

The San Xavier Indian Reservation occupies the central and southern portions of this 1968 field-checked landscape, where the high desert terrain transitions from the open Avra Valley into increasingly complex topography. Settlement is sparse, characterized by isolated sites such as J Bar M and Huff, which sit alongside a network of primitive transportation routes including the Sandario Road and various unnamed Jeep Trails.

The presence of numerous water infrastructure labels, such as Water Tanks and Wells, indicates the critical importance of water management for cattle ranching or habitation in this arid environment. This survey captures a specific moment in Pima County history, documenting the rural infrastructure and land use patterns before later 20th-century developments reached this portion of the reservation.
