About this map

The Petrified Forest National Monument Boundary defines the western portion of this mid-century landscape, where the high desert terrain transitions toward the prominent Puerco Ridge. This region is characterized by a sophisticated network of water management features essential for ranching and survival in the arid environment. Numerous named reservoirs, such as Blue Tank, Doubtful Tank, and Waterhaul Tank, are scattered across the terrain to catch runoff from seasonal drainages like Ninemile Wash and East Fork Dry Creek. The prominence of Black Knoll serves as a central landmark amidst the undulating topography. The mapping reflects a moment before the widespread modernization of the area, capturing the critical relationship between the seasonal flow of the Puerco R and the livestock infrastructure that sustained local land use during the 1950s.
