1947 Map of Santa Rosa

About this map

San Pablo Bay and the northern reaches of the San Francisco Bay Area are documented here at a mid-century turning point. The landscape is defined by the heavy rail influence of the Northwestern Pacific and Southern Pacific lines, which connect agricultural centers like Santa Rosa and Napa to the industrial waterfronts of Vallejo and Benicia. This era shows the region before the post-war suburban explosion, where the Berryessa Valley and Carrell Valley remain distinct geographic features and the Mayacmas Mountains separate the coastal drainages from the interior.
