Yorkville and The Oaks serve as the primary residential anchors in this part of Mendocino County, where the landscape is defined by the high ridges separating the Sanel Valley from the surrounding highlands. The complex hydrology of the region is evident in the numerous drainages such as Feliz Cr, Cummiskey Cr, and Elkhorn Cr, which carve through the terrain between prominent peaks. These elevations, including Duncan Peak, Snow Mtn, and Lookout Mtn, dominate the horizon and provide the vertical relief that historically influenced road placement and land use. Local landmarks such as Pregnant Spring and Saddle Spring indicate reliable water sources in a terrain otherwise characterized by steep slopes and narrow valleys. This map illustrates the modern road network, from Old Hopland 110 Rd to the more specialized Pomo Tierra Ranch Rd, reflecting the continued importance of these routes for ranching and rural access.
