1955 Map of Sunset Pass

About this map

West Sunset Mountain and East Sunset Mountain dominate this mid-century Coconino County landscape, separated by the strategic corridor of Sunset Pass. The survey, completed in cooperation with the Atomic Energy Commission, reflects a rugged High Desert environment defined by water management and ranching infrastructure. Numerous named water catchments like Porcupine Tank, Hobo Tank, and Rowlan Tank are scattered throughout the territory, illustrating the essential nature of water storage for livestock and local operations. The winding course of Clear Creek carves through the southern portion of the sheet, while Jacks Canyon cuts across the central plains. This 1950s record provides a look at the arid periphery of the Coconino National Forest, where the presence of the Winslow Municipal Well Field and several prospect pits indicate the ongoing industrial and municipal utility of the land during the atomic era.
