1958 Map of Clearlake Highlands

USGS Topo · Published 1978

About this map

The south shore of Clear Lake serves as a vibrant focal point for development in the Lake County hills during the mid-20th century. The communities of Clearlake Highlands and Clearlake Park show significant expansion, anchored by Burns Valley and the Burns Valley Sch. This era captures the region's character as both an industrial site and a recreational destination, with the Sulphur Bank mine situated near the shores of Borax Lake while specialized retreats like Salminas Resort and Mt Hannah Lodge occupy the higher elevations to the south. The presence of two airfields, Hoberg Airport and Pearce Airport, suggests a landscape increasingly connected by air travel. Between the shoreline and the peaks of Seigler Mtn and Mt Hannah, a complex network of seasonal lakes including Thurston Lake and Dry Lake punctuates the terrain, illustrating the unique drainage patterns that define this volcanic geography.
