About this map

Cottaneva Valley and the surrounding Mendocino County ridges are defined by a complex network of coastal drainages and historical ranching activity in the early 1970s. The settlement of Hales Grove serves as a small interior hub, while Dutchmans Flat and the DeVilbiss Ranch mark localized sites of habitation and land use. Along the western edge, the rugged coastline is dotted with maritime landmarks like Shoreline Rock, Usal Rock, and Sea Lion Rock, highlighting the interface between the Pacific Ocean and the steep terrain of Timber Ridge.

Transportation through this difficult landscape is anchored by Usal Road, providing access to the canyon of Usal Creek and its many tributaries, including Shady Dell Creek and Julias Creek. The map also captures several family-named topographical features such as Soldier Frank Hill and Williams Point, alongside recreational spaces like the Hanky Tank Picnic Area and the northeastern corner of the Standish-Hickey State Recreation Area.
