1943 Map of Calistoga

About this map

The volcanic terrain of the Mayacamas Mountains dominates this 1940s survey, illustrating a landscape defined by mercury and silver mining. Centered on Mount St Helena, the map details a complex web of industry where the Silverado Mine (abandoned) and Great Western Mine once operated alongside newer prospects like the Aetna Extension Mine. In the valley below, the Southern Pacific railroad terminates at Calistoga, a hub connecting the agricultural Napa River floor to the high timber and mineral claims. Rural life is anchored by a network of one-room schools, including Franz Valley Sch and Alpine Sch, while the famed Petrified Forest stands as a distinct geological landmark. The presence of the Toll House on the road north toward Middletown highlights the historical transit routes used before modern highway development bypassed these steep mountain passes.
