About this map

San Carlos serves as a central hub within the San Carlos Indian Reservation in the mid-1960s, situated at the confluence of the San Carlos River and Sevenmile Wash. The settlement pattern reflects the administrative and community infrastructure of the era, featuring the Indian Agency, a Hospital, and a Substation along the Southern Pacific railroad line. This corridor follows the river valley southward through Peridot, where the landscape transitions toward the striking topography of Peridot Mesa.

Water management is critical in this arid Gila County landscape, evidenced by numerous named tanks such as Maltazan Tank and Telephone Tank. The map also captures local community spaces like the Rodeo Grounds and an early Gaging Station on the river. Beyond the developed valley, the terrain rises into the highlands of Hackberry and Triplet, dissected by ephemeral drainages like Hackberry Creek and Apache Wash.
