About this map

Clear Lake defines the southern edge of this landscape, where the settlements of Clearlake Oaks and Glenhaven line the shoreline. The northeast arm of the lake is marked by several prominent islands, including Anderson Island, Weekend Island, and Rattlesnake Island, situated just off the coast from Stubbs Island. To the north, the terrain rises sharply into the High Valley Ridge and the southern reaches of the Mendocino National Forest.

Evidence of local industry and rural life is scattered throughout the hills, most notably at the Sulphur Bank Mine and the Sulphur Bank Rancheria near the lake's edge. Historical researchers can identify family-named sites like the Garner Ranch and Kennedy Ranch tucked into the canyons, alongside the East Lake Sch. The map also captures the varied topography of High Valley, a flat agricultural or grazing basin surrounded by ridges and peaks like Evans Peak and Round Mtn.
