1958 Map of Cow Mountain

USGS Topo · Published 1960

About this map

Cow Mountain and the surrounding Mayacmas Mountains dominate this 1958 survey along the Mendocino and Lake County boundary. The landscape is defined by ranching life and rugged watercourses, where isolated homesteads like Lamb Ranch, Hemlock Ranch, and Cow Mountain Ranch are connected by a network of trails and firebreaks. The topography transitions from high peaks such as Shell Peak and the Forty-Acre Opening down into the narrow drainage of Cold Creek. To the east, the terrain breaks at Blue Lakes, with The Narrows and Lower Blue Lake marking a significant geological and recreational boundary in the valley. The presence of numerous named springs, including Black Oak Springs, highlights the critical importance of water management in this upland environment during the late 1950s.
