1966 Map of Yellow Hill

About this map

The Navajo Indian Reservation landscape in San Juan County is defined by a network of ephemeral watercourses and distinct geological formations as documented in the mid-1960s. The terrain is marked by significant features such as the Rock Ridge and the eponymous Yellow Hill, alongside Tocito Dome. Water management in this arid environment is evident through labels for the Big Gap Reservoir and several instances of a Flowing Well, which supported local grazing as indicated by a Corral in the northern sector. Infrastructure is sparse but purposeful, following the Red Rock Highway and a prominent industrial Pipeline that cuts across the high desert. Researchers can trace the path of Dead Mans Wash and Pajarito Creek as they drain through this territory, which also shows signs of resource exploration via a solitary Drill Hole.
