1958 Map of Wilson Valley

About this map

Cache Creek winds through this northern California landscape, carving a deep path through the canyon lands of the Coast Ranges at the end of the 1950s. The map illustrates a transitional terrain where the borders of Lake, Colusa, and Yolo counties converge. Remote valleys like Wilson Valley and the broader Morgan Valley provide a stark contrast to the surrounding heights of Little Blue Ridge and Grizzly Peak. This survey is particularly useful for identifying the specific locations of water sources in an arid region, such as Dunfield Spring and Bear Spring. Landmarks like The Peninsula and Kennedy Flats reveal the complex topography of the watershed, while numerous jeep trails and canyon names like Stemple Canyon and Thompson Canyon suggest a history of grazing and transit through these high basins.
