2017 Map of Horsehead Canyon NW

About this map

Rio Nutria flows through this high-desert landscape in the Eastern Navajo Agency, defining a corridor of vital water management in a drainage-carved terrain. The map documents a sophisticated series of catchments, including Nutria Reservoir Number 4, Nutria Reservoir Number 3, and Nutria Reservoir Number 2, which supported the region's agricultural and pastoral needs. The topography is deeply etched by seasonal watercourses and canyons, such as Coal Mine Canyon and Burned Timber Canyon, which demonstrate the natural erosion patterns of the McKinley County area. An extensive network of Bureau of Indian Affairs roads, such as Indian Svc Rte 7 and Indian Svc Rte 29, provides the primary infrastructure connecting these remote drainage basins and grazing lands, while the southern edge of the sheet transitions toward the Rio Pescado valley.
