About this map

Clear Lake defines the southern reach of this 1960s survey, where the resort communities of Clearlake Oaks and Glenhaven line the northern shore near Honeymoon Cove. The landscape transitions northward into the steep ridges and canyons of the Mendocino National Forest, a terrain marked by numerous thermal and mineral sites such as Bartlett Springs, Hough Springs, and Allen Springs.

Industrial activity is anchored by the Sulphur Bank Mine near the lake's edge, while the interior's pastoral and forestry character is evidenced by scattered outposts like the Pacific Ridge Guard Station and Wilson Camp. The rugged drainage systems of Cache Creek and Wolf Creek carve through the high country, connecting isolated points like Barkerville with the broader valley flats. This map records the region as it balanced lakefront development with the older extractive and seasonal economies of the California Coast Ranges.
