1965 Map of Fortuna SW

About this map

The Yuma Desert landscape dominates this 1960s survey, defined by the expansive Luke Air Force Range. This area is characterized by shifting sands and alluvial plains, marked by specific military training features such as a Target and Arena 432. The map details the precise topography of the desert floor, with scattered benchmarks and various survey markers like Guide and Target lines crossing the terrain. A sparse network of Jeep Trails provides the only recorded access through this arid environment, connecting to an Approximate West Route in the northeastern corner. Mapping this quadrant involved a multi-agency effort, synthesizing data from the Bureau of Reclamation and aerial photography to document the desert's changing surface during the mid-20th century.
