San Diego Country Estates occupies the lower center of this survey, showing the residential footprint of this planned community south of the Santa Maria Valley. To the north, the terrain rises into the Cleveland National Forest, where the Lake Sutherland reservoir is held by a dam along the Santa Ysabel Creek. The landscape is a series of distinct valleys, including Pamo Valley, Goose Valley, and Ballena Valley, each separated by significant peaks such as Whale Mountain and Mount Gower. Local history and aviation are noted through the presence of the Flying T Ranch Airport and several burial grounds, including Ballena Cemetery and Nuevo Memory Gardens. The network of backroads like Black Canyon Road and Sutherland Dam Road provides a view into how the rural spaces between these valleys were accessed in the late 2010s.
