About this map

Tonalea and the Red Lake post office serve as the primary landmarks in this 1970 landscape, where the Navajo Indian Reservation and Hopi Indian Reservation meet. The map documents a period of administrative and topographical transition, clearly marking the Old Indian Reservation Boundary alongside more modern infrastructure like the prominent north-south Pipeline.

Hydrological features are critical in this arid environment, evidenced by named water sources such as Mormon Well, Bitter Well, and Side Rock Well. Local history and geology are captured through specific markers like the George Smith Hist Mon and the distinctive geological formations of the Elephant Feet. The map's detail extends to local commerce and infrastructure, including a Trading Post, a Rest Area, and Sewage Disposal Ponds, providing a clear record of the high desert's 20th-century development.
