About this map

Alexander Valley agriculture and the winding path of the Russian River define this mid-century portrait of northern Sonoma County. The valley floor is a patchwork of ranching and viticulture, evidenced by the Winery near the foot of Black Mountain and various family-operated sites like Ridge Ranch and Douglas Ranch. Early settlement patterns are preserved in the naming of the Beeson Cemetery and local institutions such as the Alexander Valley School and Allan Sch.

The landscape transitions from the river's fertile basin to the mineral-rich slopes of Caslamayomi, where mining activity is marked by the Mericoma Quicksilver Mine and a Manganese Mine. Transportation is anchored by the Northwestern Pacific railroad, which parallels the river and serves the communities of Lytton and Chiquita. The presence of several historic tribal lands, including the Lytton Rancheria and Alexander Valley Rancheria, provides a window into the complex human geography of the region before late-20th-century development.
