1966 Map of Ship Rock

About this map

The geological landmark Ship Rock dominates this mid-1960s topographic survey of the Navajo Indian Reservation. This map reveals the striking volcanic topography of the high desert, including the prominent radiating Dike structure that extends southward from the central peak. Beyond the geological features, the landscape is defined by the energy infrastructure of the era, specifically the Rattlesnake Oil Field and the Shiprock-Gallup Oil Field. A network of access roads, an industrial Pipeline, and various marked Drill Holes illustrate the intersection of traditional land and modern resource extraction. Drainage patterns are represented by the seasonal paths of Shiprock Wash and Rattlesnake Wash, while the Red Rock Highway provides the primary transit route through this remote section of San Juan County.
