1958 Map of Clearlake Oaks

About this map

Clear Lake dominates the southern landscape of this mid-century survey, with the waterfront communities of Clearlake Oaks and Glenhaven emerging as key population centers along the northern shore. The era is defined by a mix of agricultural ranching and industrial extraction, most notably at the Sulphur Bank Mine situated near Sulphur Bank Point. Inland, the terrain rises sharply into High Valley and the Mendocino National Forest, where established family holdings like Garner Ranch and Kennedy Ranch occupy the more level ground of Long Valley. Local infrastructure of the late 1950s is evidenced by the East Lake Sch and the Fire Control Station near the narrows. The map also documents the Sulphur Bank Rancheria and several prominent islands, including Rattlesnake Island and Anderson Island, which characterize the complex shoreline of this volcanic lake region.
