1949 Map of Briones Valley

USGS Topo · Published 1949

About this map

San Pablo Reservoir dominates the western canyons of this Contra Costa County landscape, serving as a focal point for the complex drainage systems of Bear Creek and San Pablo Road. The interior is defined by the sharp relief of the Briones Hills and the sprawling La Boca de la Canada del Pinole, where the rural character of the late 1940s is still evident. Small clusters of development at Orinda Village and Lafayette sit at the southern edge, while the northern reaches remain sparsely settled, marked only by the Atchison Topeka and Santa Fe line and the isolated Briones Valley Sch.
