1968 Map of May Lake

About this map

The dramatic transition from the high South Warner Rim down into the expansive Warner Valley dominates this 1968 topographic survey. This area of Lake County is defined by its vital water sources in an otherwise arid landscape, including May Lake and numerous named springs such as Surveyor Spring and Spearpoint Spring. The map documents a rugged cattle-ranching and range environment where seasonal water management is critical, evidenced by the Gaging Station on Twentymile Creek and the presence of Lucky Res.
