1966 Map of Yellow Hill

About this map

The Navajo Indian Reservation landscape is defined by the high desert topography of San Juan County, dominated by the prominent elevation of Yellow Hill and the geological formation of Tocito Dome. This mid-century survey captures a network of resource extraction and water management infrastructure, including an extensive Pipeline and a remote Corral in the northern sector. The terrain is deeply incised by seasonal watercourses such as Dead Mans Wash and Pajarito Creek, which are critical features in this arid environment. Evidence of industrial exploration is visible through a documented Drill Hole and several instances of a Flowing Well, highlighting the search for subsurface resources. The western edge of the quadrangle is anchored by the natural barrier of Rock Ridge, while the Red Rock Highway provides the primary transit artery through this corner of the reservation.
