1959 Map of Las Trampas Ridge
USGS Topo · Published 1969About this map
St Marys College and the surrounding valley floor are shown during a period of rapid suburban expansion in central Contra Costa County. While established residential centers like Lafayette, Alamo, and Danville are well-defined, purple photorevision overlays reveal the late-1960s footprint of new housing developments creeping into the foothills of Las Trampas Ridge and Rocky Ridge. The corridor follows the Southern Pacific railroad line through the San Ramon Valley, where local landmarks like San Ramon Valley HS and Stone Valley Sch served the growing population.
