1951 Map of Sonoma

About this map

Sonoma sits at the heart of the valley floor, surrounded by the Pueblo Lands and a landscape transitioning from agricultural vine plantations to mid-century residential expansion. This 1951 survey records the historical significance of the region, identifying the Vallejo Home State Historical Monument and the Mission San Francisco Solano Vineyard. Along the western edge of the valley, the thermal resort culture is evident through a string of settlements including Agua Caliente, Fetters Hot Springs, and Boyes Hot Springs. The map also captures the evolving transportation network, showing the Northwestern Pacific RR line and a Dismantled RR route that hints at earlier transit patterns. Education and industry are well-marked, from the Mount La Salle School in the eastern hills to several Quarries and a Gravel Pit near Verano. The rugged eastern backdrop is defined by Bismarck Knob and Hogback Mtn, where steep canyons like Redwood Canyon descend toward the fertile valley floor.
