About this map

The Navarro River snakes through the northern reaches of this coastal range landscape, defining a terrain of steep ridges and clearings in Mendocino County. Higher elevations are marked by distinctive landmarks such as Cold Spring Mtn and Greenwood Ridge, which served as critical navigation points and hubs for local timber and ranching operations. The presence of named openings like Kane Opening, Hamilton Opening, and Brushy Opening indicates historic clearings within the dense forest cover, often associated with early homesteads or seasonal grazing.

Settlement is concentrated around Reilly Heights in the northeast, while a complex network of forest roads, including Philo Greenwood Rd and Signal Ridge Rd, provides access across the various drainages. Water sources like Soda Spring and Three Springs dot the landscape, feeding into a dense web of creeks such as S Fork Greenwood Cr and Mallo Pass Cr. These features reflect the area's history as a working landscape where geography dictated the placement of roads and small mountain communities.
