Cottaneva Valley and the surrounding Mendocino County coastline are characterized by a network of steep gulches and coastal ridges meeting the Pacific Ocean. This survey highlights the intersection of modern recreation and historical utility, with the Lost Coast Trail tracing the shoreline while Timber Haul Rd and Hollow Tree Creek Rd reveal the legacy of the local timber industry. The small settlement of Hales Grove sits near the headwaters of the S Fork Mule Cr, adjacent to the high flats of Dutchmans Flat.
