2012 Map of Arched Rock

About this map

Arched Rock and the shoreline of Sonoma County define this coastal landscape, where the Pacific Ocean meets a series of steep drainages and rocky outcrops. The map illustrates a complex network of coastal ravines, including Mill Gulch, Timber Gulch, and the multi-branched Russian Gulch, which feeds Russian Gulch Creek as it approaches the sea. Inland, the elevation rises toward Little Black Mountain, while the winding Meyers Grade Rd provides the primary transit route through this terrain.
