1970 Map of Hales Grove

USGS Topo · Published 1974

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.
