About this map

Clear Lake dominates this landscape, its southern shoreline marked by a series of developed communities and distinctive geological features. The settlement of Clearlake Highlands serves as a focal point near the southern basin, while to the west, residential enclaves like Riviera West and Clear Lake Riviera wrap around Konocti Bay. The presence of the Konocti-Clear Lake Seaplane Base indicates the lake's importance for aviation and regional access beyond simple recreation.

Further inland, the terrain transitions into a series of smaller basins and ridges, including Borax Lake to the north and the secluded Thurston Lake to the south. Notable landmarks such as Salminas Resort and Mount Hannah Lodge reflect a long-standing history of tourism and retreat in the shadow of Mount Hannah. The landscape is a mix of dense residential grids in Clearlake and wide, open flats like Plum Flat and Hesse Flat, illustrating the varied topography of this volcanic region.
