2021 Map of Clearlake Oaks

About this map

The northeastern shoreline of Clear Lake defines this landscape, where the settlements of Clearlake Oaks, Glenhaven, and Indian Beach cling to the waterfront beneath the rising elevation of the California Coast Ranges. The topography transitions sharply from the lake's surface to the interior ridges of the Mendocino National Forest, characterized by numerous canyons such as Sulphur Canyon and Bald Hill Canyon. Notable landforms along the water include Sulphur Bank Point, Paradise Point, and several islands like Rattlesnake Island and Stubbs Island. Inland, the geography is marked by the broad High Valley and Long Valley, which are drained by Schindler Cr and Long Valley Cr. This modern survey details the complex network of local roads and fire trails, including Co Rd 221 and High Valley Rd, that navigate the steep terrain between the lake and summits like Evans Peak.
