1966 Map of Mosquito Valley

About this map

Mosquito Lake sits at the heart of this high desert basin in northern Washoe County, a centerpiece of the broader Mosquito Valley landscape. The 1960s survey reveals a territory defined by its scarce water resources and ephemeral drainage, where naming conventions like Gravelly Spring and various unnamed Springs and Seeps denote the vital importance of surface water in an otherwise arid environment. To the south, the terrain drops into the Long Valley (Depression), a vast sink that collects runoff from the surrounding hills. Human presence is marked primarily by a network of primitive Jeep Trails and footpaths, suggesting a region used for cattle ranching or seasonal grazing rather than permanent settlement. The lack of structures or roads highlights the isolation of this corner of the Great Basin at the time of the field check.
