2021 Map of Greenough Ridge

USGS Topo · Published 2021

About this map

Greenough Ridge and the Greenough Roughs dominate this portion of Mendocino County, where the landscape is defined by the complex drainage of the Big River and its various branches. The area is marked by numerous family-named openings and high points, such as the Hans Ottoson Opening and Williams Peak, suggesting a history of high-elevation ranching and forestry. Narrow access roads like Muir Mill Rd and Williams Ranch Rd wind through the hills, providing connections between isolated points like Irene Peak and the drainage of Baechtel Cr. The density of named gulches, including Pigpen Gulch and Bowman Gulch, reflects a deeply dissected terrain where water management and timber access were likely primary concerns for local residents and landowners in the 21st century.
