Calaveras Reservoir dominates the northern landscape of this survey, fed by the waters of Arroyo Hondo and Calaveras Creek. The rugged eastern ridges, including Oak Ridge and Poverty Ridge, stand in contrast to the rapid urban expansion emerging in the San Jose and Milpitas areas to the southwest. This 1961 edition, updated with 1968 purple revisions, documents the post-war transition of agricultural valleys into suburban residential clusters.
