The Russian River defines the western valley floor in this late 20th-century survey, winding through the rich agricultural lands of the Alexander Valley and Musalacon. The small settlement of Asti serves as a focal point near the river, home to the Our Lady of Carmel Church and a modern Water Filtration Plant. To the east, the terrain rises sharply into the Mayacmas Mountains and Pine Mountain, a landscape marked by steep canyons such as Devils Den North and Big Sulphur Creek. The presence of the Cloverdale Municipal Airport and a Radio Repeater Station indicates the infrastructure supporting this portion of Sonoma County. Complex land divisions are evident through various Grant Boundary markings, illustrating the persistent influence of historical land grants on modern Californian geography.
