Lake Sonoma dominates this portion of Sonoma County, its intricate shoreline formed by the flooding of deep valleys behind the Warm Springs Dam. The hydrology of the region is defined by a dense network of drainages including Warm Springs Cr, Rancheria Cr, and the appropriately named Little Warm Springs Cr. The surrounding terrain rises sharply to prominent landmarks such as Pritchett Peaks and Bummer Peak, while the southern reaches of the map transitions into the sheltered depths of Redwood Canyon and Wildcat Canyon.
