USGS Topo · Published 1984About this map
Mt Diablo State Park dominates the northern reaches of this landscape, where the Black Hills and Fossil Ridge rise sharply above the developing San Ramon Valley. The 1953 survey, with updates from 1980, captures a pivotal era of suburban expansion in Contra Costa County. Early infrastructure like the San Ramon Valley Branch railroad and San Ramon Siding sits alongside educational foundations such as Green Valley School and the Athenian Sch.
