Lake Lahontan

Lake Lahontan was a large endorheic Pleistocene lake of modern northwestern Nevada that extended into northeastern California and southern Oregon. The area of the former lake is a large portion of the Great Basin that borders the Sacramento River watershed to the west.
History
At its peak approximately 12,700 years ago (during a period known as the Sehoo Highstand), the lake had a surface area of over 8,500 square miles (22,000 km2), with its largest component centered at the location of the present Carson Sink. The depth of the lake was about 900 feet (270 m) at present day Pyramid Lake, and 500 feet (150 m) at the Black Rock Desert. Lake Lahontan, during this most recent glacial period, would have been one of the largest lakes in North America.
Climate change around the end of the Pleistocene epoch led to a gradual desiccation of ancient Lake Lahontan. The lake had largely disappeared in its extended form by about 9,000 years ago. As the surface...
