1966 Map of Sanostee East

About this map

The high desert landscape of the Navajo Indian Reservation in San Juan County is defined here by a series of prominent geological formations and the early infrastructure of energy extraction. The map reveals the Tocito Dome Oil Field in the northeast, where pipelines and access roads cut across the arid terrain. Natural water sources are scarce but critical, evidenced by Tocito Springs and the sprawling drainages of Sanostee Wash, Tocito Wash, and Pajarito Creek. Significant topographic landmarks such as the massive Rock Ridge and the isolated Rock Mesa provide clear orientation points across the high-altitude plateau. A single Drill Hole noted in the west suggests the ongoing exploration of the region's mineral wealth during the mid-1960s, while the rugged Porcupine Canyon marks the dramatic relief found in the southern reaches of this Navajo Nation territory.
