1966 Map of Mosquito Valley

About this map

Mosquito Valley defines the core of this Washoe County landscape, captured during a 1966 field check of 1965 aerial photography. The terrain is characterized by a stark high-desert hydrology where seasonal water sources and small seepages are critical landmarks. The intermittent waters of Mosquito Lake sit at the center of the valley, surrounded by numerous named springs such as Gravelly Spring and various unnamed Springs and Seeps. To the south, the map transitions into the Long Valley (Depression), a vast basin where the elevation drops below 5,550 feet. The sparse human footprint in this era is represented primarily by a network of unimproved Jeep Trails that navigate the slopes and valley floors, connecting these vital water points across the high desert basin.
