About this map

The Alexander Valley floor and the surrounding high ground of Black Mountain define this mid-century survey of Sonoma County. Along the banks of the Russian River, the landscape is a mix of agricultural enterprise and indigenous heritage, marked by the Lytton Rancheria, Dry Creek Rancheria, and Alexander Valley Rancheria. The settlement at Jimtown serves as a local hub, while the Northwestern Pacific railroad tracks flank the western edge of the valley near Lytton.

Resource extraction and ranching history are evident in the upland areas, where the Meriocoma Quicksilver Mine and a Manganese Mine suggest the region's mineral value. Family-named landmarks like Ridge Ranch, Douglas Ranch, and the Beeson Cemetery provide specific points of interest for genealogists tracing the early settlers of the Sotoyome and Tzabaco land grants. The presence of the Alexander Valley School and an abandoned school reflects the shifting population centers of the 1950s.
