Description

This 1925 air navigation map, an experimental endeavor by the Engineer Reproduction Plant of the U.S. Army, delineates the aerial route from Rock Springs, Wyoming to Salt Lake City, Utah, highlighting a range of elevations and significant topographical details essential for early aviators. As an artifact from the burgeoning era of air travel, it captures the intersection of military strategy and navigational science, offering a rare glimpse into the planning required for early 20th-century aviation.

In the broader context of the interwar period, a time marked by technological innovation and a shift toward modern forms of transportation, this map reflects the intense focus on developing reliable and standardized methods for air navigation. The detailed depiction of gradients, landforms, and constructed features such as railroads and landing fields underscores the period's technological advancements and the critical importance of accurate, comprehensive aerial maps in enhancing safety and efficiency in aviation.

Produced by the Corps of Engineers under the auspices of the U.S. Army's Airways Section Office Chief of Air Service, the map illustrates the military's role in pioneering aviation technology and infrastructure. Its compilation at the Engineer Reproduction Plant, Washington Barracks, signifies a concerted effort to support and improve the nation's aerial capabilities, indicative of broader strategic interests in air power and national defense during a time of significant geopolitical shifts.
