About this map

Greenough Ridge and the surrounding Mendocino County backcountry are defined by the winding course of the Big River and its major tributaries, including the North Fork Big River and East Branch North Fork River. This 2012 survey illustrates a landscape primarily shaped by timber interests and ranching, where remote outposts like Fordice Ranch and Williams Ranch are connected by a network of private and service roads such as Muir Mill Rd and Williams Ranch Rd.

Distinctive topographical markers like Irene Peak and Williams Peak rise above the drainage basins, while named clearings such as Upper Ranch Opening and Hans Ottoson Opening suggest historical land use patterns in an otherwise densely wooded region. The map also traces several named gulches and brooks, including Pigpen Gulch and Russell Brook, providing a detailed look at the drainage systems that feed into the larger river network before it reaches the Pacific coast.
