USGS Topo · Published 1966About 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.
