The Russian River defines the fertile valley floor of this northern Sonoma landscape, winding through the historic Sotoyome and Caslamayomi land grants. Cultivation and industry concentrate along the river's path, where the Northwestern Pacific railroad corridor passes through Lytton and the northern outskirts of Healdsburg. This 1990s revision captures the area's agricultural identity, marked by prominent labels like Red Winery Road and the small crossroads settlement of Jimtown. The Alexander Valley Community Church and Alexander Valley Sch serve as local landmarks for the valley's rural residents.
