1986 Map of Tom Thumb

About this map

The Sauceda Mountains dominate this high-desert landscape in the mid-1980s, where the peaks of Tom Thumb and the passage at Pistol Pass overlook a complex network of arid drainage systems. This area is defined by its administrative and natural boundaries, sitting at the junction of the Luke Air Force Range and the Papago Indian Reservation. The terrain is deeply etched by numerous seasonal watercourses, including Sauceda Wash and Hickiwan Wash, which feed into the broad Hickiwan Valley at the southern edge of the sheet. The map also records the county line where Maricopa Co meets Pima Co, providing a clear record of land use and division in this remote section of the Sonoran desert during the late twentieth century.
