About this map

The Old Overland Stage Route cuts through this arid landscape, serving as a primary corridor for travel before modern highways. This 1942 survey by the Corps of Engineers documents a transition in transportation, centering on the Old Carrizo Stage Station along Carrizo Creek. The presence of the San Diego and Arizona Eastern RR winding through the In-Ko-Pah Mtns to the south illustrates the difficult engineering required to bridge the San Diego and Imperial County line.

Scientific and historical markers are noted across the terrain, including Prehistoric Animal Tracks near the Fish Creek Mtns and the Imperial Highway Monument further south. The map identifies critical water sources in a desert environment, such as Mountain Palm Springs and Pamitas Spring, which were vital for early travelers and livestock. From the heights of Carrizo Mtn to the depths of Fossil Canyon, the sheet provides a precise look at the geography during the early years of World War II.
