The ridge-and-canyon topography of northwestern Sonoma County defines this 2018 survey, centered on the community of Annapolis. The landscape is dominated by the complex drainage systems of the Wheatfield-Fork Gualala River and the South Fork Gualala River, which carve deep valleys between high points like Fuller Mtn and Nob Hill. Traces of the region's geological and industrial history are evident in the path of the San Andreas Fault crossing the southwest corner and the presence of the Clipper Mill Bridge over the river. Many landmarks bear the names of early settlers and landowners, preserved through features such as John West Ridge, Evans Ridge, and Miller Ridge. The map also records vital community sites, including the Annapolis Church Cem and Sugarloaf Cem, providing a detailed look at the rural road network connecting these remote points, from Stewarts Point-Skaggs Springs Rd to Tin Barn Rd.
