The Calaveras Reservoir dominates the rugged transition between the Alameda and Santa Clara county line, where the high ridges of Oak Ridge and Poverty Ridge descend into the northern Santa Clara Valley. This 1961 field-checked survey, updated in 1980, documents the suburban expansion of Milpitas and San Jose as they push toward the foothills of the Los Buellis Hills. The map captures a mix of industrial and civic development, showing numerous quarries and gravel pits alongside established institutions like the San Jose Country Club and the Spring Valley Golf Club.
