1959 Map of Highland Springs

About this map

The Mayacmas Mountains dominate this 1959 survey of the California landscape, where the rugged terrain of the Lake Co Mendocino Co boundary meets the agricultural potential of Big Valley. The map centers on the Highland Springs area, featuring the established Mineral Spring and Gaging Station along Highland Springs Creek. Human activity is concentrated in the northeast corner at the Big Valley Community Center and near the Lampson Airport, while the higher elevations are marked by remote landmarks like Cloverdale Peak, Monument Peak, and Gulliam Rock. Water resources are a primary focus of this topography, documented by the State of California Department of Water Resources. The network of drainage including Manning Creek, Adobe Creek, and Pieta Creek illustrates the complex watershed management necessary in these coastal ranges before more modern development reached the higher valleys like Donovan Valley and High Valley.
