2011 Map of National Tank

About this map

National Tank and Potters Hole sit at the center of this 2011 survey, marking the scarce water resources of the high-desert landscape in Coconino County. The area is defined by its drainage patterns and the critical network of tribal and local routes. Seasonal watercourses like Sandstone Wash and Albers Wash cut through the terrain, illustrating the hydrologic reliance of this region on intermittent flows. The map details the junction of Indian Service Road 18 and Hualapai Hilltop Rd, which serve as vital transit corridors through the territory. Further south, Sink Tank provides another grounded reference point for land management and local navigation in an area characterized by its wide-open spaces and essential water-catchment features.
