About this map

The San Andreas Rift Zone carves a distinct path through this section of Sonoma County, defining the complex topography of ridges and drainage basins. The small community of Annapolis sits atop a high ridge, anchored by the Horicon Sch, while the Stewarts Point Rancheria occupies land further south. The landscape is a network of ridges named for early settlers and families, including John West Ridge, Evans Ridge, and Hoover Ridge, with several small landing strips positioned on the flatter high-ground spurs.

Water plays a central role in the geography here, with the North Fork Gualala River and South Fork Gualala River joined by the Wheatfield Fork Gualala River. Civil infrastructure is visible in landmarks like the YMCA Camp Footbridge and the Mendocoma Forest Fire Sta. The presence of the Soda Springs (Site) and various lookout points, such as Hoover Lookout Tower, suggests a history of resource management and early settlement patterns before the more modern forest service installations.
