USA – November 25th, 2012

Visible in this image is California’s Central Valley, a large, flat valley that dominates the central portion of the state. The valley stretches approximately 450 miles (720 km) from northwest to southeast inland and parallel to the Pacific Ocean coast. It covers an area of approximately 22,500 square miles (58,000 km2), making it slightly smaller than the state of West Virginia and about 13.7% of California’s total area.

Its northern half is referred to as the Sacramento Valley, and its southern half as the San Joaquin Valley. The Sacramento Valley receives about 20 inches of rain annually, but the San Joaquin is very dry, often semi-arid desert in many places. This difference in dryness is suggested by the greener color of the northern half, and the more extensive presence of agricultural areas.

The two halves meet at the huge Sacramento-San Joaquin River Delta of the Sacramento and San Joaquin Rivers, which along with their tributaries drain the majority of the valley. The Delta is a large expanse of interconnected canals, streambeds, sloughs, marshes and peat islands.

The Southern Tip of California’s Central Valley

The Central Valley is a large, flat valley that dominates the central portion of the U.S. state of California. It is home to many of California’s most productive agricultural efforts, many of whose fields create green and brown checks in the image.

The valley stretches approximately 400 miles (600 km) from north to south. The southern half  is known as the San Joaquin Valley; this image focuses on the southernmost end.

The flatness of the valley floor contrasts with the rugged hills or gentle mountains that are typical of most of California’s terrain.

It is bounded by several mountain ranges, including the Sierra Nevada to the east, the Tehachapi Mountains to the south, and the Coastal Ranges to the west.

The high Sierra Nevada Mountains around Lake Tahoe (top right), California, are capped with snow, thus living up to their name, translated as “snow-covered mountain range”.

The mountains slope down into California’s Central Valley, which stretches approximately 400 miles (600 km) from north to south. Its northern half is referred to as the Sacramento Valley, where the city of Sacramento is located, and its southern half as the San Joaquin Valley, home to cities such as San Francisco. Both cities are visible here: Sacramento towards the center, and San Francisco along the coast (bottom left).

San Francisco Bay is visible along the coast, its waters containing some golden brown sediments. The bay is a shallow, productive estuary through which water draining from approximately forty percent of California, flowing in the Sacramento and San Joaquin rivers from the Sierra Nevada mountains, enters the Pacific Ocean.

Lakes Near California-Nevada Border, USA

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.

Sierra Nevada Mountains and San Joaquin Valley, California – December 21st, 2008

Sierra Nevada Mountains and San Joaquin Valley, California - November 17th, 2008

We have here a clear view of a geographically diverse area: the Sierra Nevada Mountains, capped by snow, the green San Joaquin Valley to the West, and desertous Death Valley to the East.

The Sierra Nevada (Spanish for “snowy mountain range”) is a mountain range located in California, USA. In a few places, it overlaps into neighboring state of Nevada.

The range stretches 400 miles (650 km), from Fredonyer Pass in the north to Tehachapi Pass in the south.

The height of the mountains in the Sierra Nevada gradually increases from north to south. The entire range attains its peak at Mount Whitney (14,505 feet, 4,421 m).

The San Joaquin Valley refers to the area of the Central Valley of California that lies south of the Sacramento-San Joaquin Delta in Stockton.

Although most of the valley is rural, it does contain urban cities such as Stockton, Fresno, Visalia, Tulare, Hanford, Modesto, Bakersfield, and Merced.

The San Joaquin Valley has hot, dry summers and cool winters characterized by dense Tule fog. The rainy season occurs from November through April.

Death Valley, on the other hand, on the border of California and Nevada, is the lowest, driest and hottest valley in the United States. It is the location of the lowest elevation in North America at 85.5 m (282 ft) below sea level.

Death Valley holds the record for the highest reliably reported temperature in the Western hemisphere (134 °F (56.7 °C) It has an area of about 3,000 square miles (7,800 km²).
