Islands in Mono Lake, in California, USA

USA - March 20th, 2011

The full version of this orthorectified image shows Mono Lake, a large, shallow saline lake in Mono County, California. Because it lacks an outlet, dissolved salts make the lake very alkaline and salty.

Mono Lake is in a geologically active area at the north end of the Mono-Inyo Craters volcanic chain and is close to Long Valley Caldera. Volcanic activity continues in the Mono Lake vicinity.

Two main islands can be seen in the lake: the larger Paoha Island and the smaller Negit Island. Both islands are of volcanic origin. They are separated by a narrow channel. During low water levels, Negit Island and eventually Paoha Island become connected to the mainland in one giant peninsula. Here, the water levels are high enough so as to separate the islands.

Mountains and Lakes by Great Central Valley, California

USA - February 11th, 2011

California’s Great Central Valley bordered by mountain ranges, including the Sierra Nevada to the east, the Coast Ranges to the west, and the Tehachapi Mountains to the south.

The Sierra Nevada, as its name suggests, is capped with snow in this image. Several lakes stand out against the white backdrop, the largest of which are Lake Tahoe (near top edge) and Mono Lake (below the former).

Several cities can also be observed in and near the valley, including San Francisco (near the coast in the upper left quadrant) and Bakersfield (near the southern edge of the valley).

Lakes Near California-Nevada Border, USA

California, USA - March 10th, 2009

Arid tan terrain near the Nevada-California border, USA, gives way to the snow-covered Sierra Nevada mountains, which slope down into the fertile green San Joaquin Valley and finally to the Pacific Ocean.

The moutainous land in the upper right quadrant is interrupted by several dark blue lakes. At the very top is Pyramid Lake, an endorheic salt lake, approximately 188 square miles (487 km²) in area, in the Great Basin in the northwestern part of the US state of Nevada.

One of the largest lakes in the United States, it is located along the east side of the Virginia Mountains with a surface elevation of about 3,790 feet (1,155 m). It is fed by the Truckee River, which enters the lake from its southern end. It has no outlet, with water leaving only by evaporation, or sub-surface seepage. The salinity is approximately 1/6th of sea water.

The large body of water to the South is Lake Tahoe, in the Sierra Nevada mountains along the border between California and Nevada.

Freshwater Lake Tahoe is the largest alpine lake in the United States. Its depth is 514 m making it the USA’s second-deepest. The lake is known for the clarity of its water and the panorama of surrounding mountains on all sides.

Two smaller lakes are visible to the East: Walker Lake (above) and Mono Lake (below). The former is a natural lake, 50.3 mi² (130 km²) in area, in the Great Basin in western Nevada, along the eastern side of the Wassuk Range. It is 18 mi (29 km) long and 7 mi (11 km) wide. The lake is fed from the north by the Walker River and has no natural outlet except absorption and evaporation.

The latter, Mono Lake, is an alkaline and hypersaline lake in California that is a critical nesting habitat for several bird species and is an unusually productive ecosystem.
