About this map

St Helena sits at the southwestern edge of this 1942 survey, serving as a hub where the Southern Pacific railroad meets the Silverado Trail along the Napa River. Moving northeast, the landscape shifts from the valley floor into the steep terrain of Howell Mountain and the Las Posadas State Forest. The community of Angwin and the nearby Sanitarium reflect the specialized institutional development of the area during the early war years.

Further into the interior, the map reveals a decentralized network of rural life in the Locallomi Valley and Pope Valley. Numerous small schoolhouses, such as Central Sch, Hardin Sch, and Chiles Valley Sch, are scattered among the ridges. Industrial and recreational markers like the Aetna Mine and Aetna Springs underscore a diverse economy based on mineral extraction and natural springs, while the remote Berryessa Valley and Putah Creek define the eastern reach of the quadrangle.
