1966 Map of East Of Grey Hill Spring

About this map

The high desert terrain of the Navajo Indian Reservation dominates this 1966 topographic survey, capturing a landscape defined by dramatic elevation changes and remote utility infrastructure. The boundary between San Juan Co and Mc Kinley Co bisects the southern portion of the sheet, cutting through an area where natural drainages and mesa formations dictate the movement of water and travel. While lacking dense settlements, the map reveals the industrial footprint of the mid-1960s through several corridors marked Pipeline, which traverse the desert to connect energy resources across the Four Corners region. These surveyed lines provide a specific record of how modern infrastructure was integrated into the traditional tribal lands during the post-war era.
