1958 Map of Mark West Springs

About this map

Petrified Forest stands as a primary landmark in this late 1950s survey of the hills between Santa Rosa and the Napa Valley line. The map highlights a landscape of historical ranching and small-scale settlement, anchored by Mark West Springs and the nearby Mark West Creek Rancheria. Ancient Spanish land grants still leave their mark through labels like Moristul y Plan de Agua Caliente and Carne Humana, reflecting the complex property history of the region. The drainage patterns of Mark West Creek and Franz Creek define the topography, while rural education centers like the Alpine School and routes such as Franz Valley School Road indicate the established community structure. From the small settlement of Fulton to the varied heights of Chalk Mtn and Sugarloaf, this map documents a era of rural Sonoma County before modern suburban expansion.
