Clear Lake dominates the upper half of this topography, reflecting a mid-century period of lakeside development centered around Clearlake Highlands and Clearlake Park. The map documents a recreational and residential landscape, featuring the Burns Valley Sch and a Drive-in Theatre near the shoreline of Burns Valley. Historical activity is evident at the Sulphur Bank and nearby Borax Lake, while the southern reaches show scattered resorts and lodges like Salminas Resort and Mt Hannah Lodge tucked into the foothills of Mt Hannah. Transportation and utility infrastructure of the era is marked by the presence of Hoberg Airport and a network of secondary routes like Soda Bay Road and Lakeshore Drive that connect the various coves and landings along the waterfront.
