About this map

The Napa River valley serves as the commercial anchor of this 1940s landscape, with Calistoga positioned at the railhead of the Southern Pacific line. The map illustrates a region transitioning from its mining peak toward an economy rooted in its unique geology and agriculture. Extensive quicksilver mining activity is evident across the heights, from the Great Western Mine in the north to the Oat Hill Mine and the Silverado Mine (abandoned) farther south.

Beyond the industrial sites, the map details a rural network of homesteads and local infrastructure, including the Petrified Forest and numerous small country schools like Alpine Sch and Riebli Sch. Settlements such as Middletown and Kellogg are connected by winding mountain roads that cross county lines between Lake, Sonoma, and Napa. The terrain is marked by significant peaks like Mount St Helena, which features a prominent Lookout, and rugged flats such as Dead Horse Flat.
