2021 Map of Cold Spring

About this map

Greenwood Ridge and Cliff Ridge define the steep, creek-cut terrain of this Mendocino County landscape. The area is characterized by high, open clearings known locally as openings, including Kane Opening, Hamilton Opening, and Brushy Opening. These named clearings suggest a history of grazing or natural breaks in the dense coastal timber. Settlement is sparse, concentrated near Reilly Heights in the northeast, while the rest of the land is defined by a network of drainage systems like Russian Gulch and the Navarro River. Roads such as Philo Greenwood Rd and Signal Ridge Rd trace the highest ground, following the natural contours of the ridges to connect the remote homesteads and ranch lands that have shaped this region for generations.
