About this map

Sacramento and the surrounding Sacramento Valley are captured here in a period of significant mid-century transition, serving as a vital hub where the Sacramento River meets an extensive rail network. The post-war landscape is defined by the expansion of military aviation at McClellan Air Force Base and Mather Air Force Base, alongside the established academic grounds of the University of California in Davis.

To the east, the map traces the ascent into the Sierra Nevada, highlighting the complex water management systems of the era, including the Hetch Hetchy Reservoir and Salt Springs Reservoir. This 1940s survey documents the critical intersections of major transit lines like U S Highway 99 and the Southern Pacific RR, illustrating how the agricultural wealth of the valley floor connected to the resource-rich mountain districts near Placerville and Jackson.
