USGS Topo · Published 1945About this map
St Helena serves as the focal point of this mid-century survey, where the Southern Pacific RR and the Silverado Trail parallel the Napa River. The landscape transitions from the valley floor into the heights of Howell Mountain, where the community of Angwin and Pacific Union College are established near the Las Posadas State Forest. Further north, the map reveals a more isolated rural network defined by Locoallomi Valley and Pope Valley, which were supported by local institutions like Central Sch and Hardin Sch.
