About this map

The Sand Hills dominate this mid-century landscape of Imperial County, California, showing a territory defined by infrastructure and military utility. The Southern Pacific railroad cuts a straight line through the desert, connecting the small settlements of Glamis and Ruthven. This corridor was critical for transcontinental freight and travel in the post-war era, even as the surrounding environment was carved into functional zones.

Large swaths of the terrain are designated as part of a Naval Reservation Boundary, including a specific Impact Range within the dunes. The map provides a detailed view of the East Mesa and the network of dikes and unimproved tracks, such as Glamis Rd, that navigated this arid region. The inclusion of numerous survey benchmarks along the rail line highlights the technical precision required to maintain transport links in shifting desert sands.
