USA – September 3rd, 2012

A thick plume of smoke is released from a wildfire north of the Sacramento Valley, the portion of the California Central Valley that lies to the north of the San Joaquin-Sacramento Delta in the U.S. state of California. The plume of smoke is thickest near its point of origin, but winds have also blown it westward, creating a thin, hazy veil over the area. Click here for previous images of wildfires in western USA.

California’s Central Valley is a large, flat valley that dominates the central portion of California. The valley stretches approximately 450 miles (720 km) from northwest to southeast inland and parallel to the Pacific Ocean coast.

The ‘Central Valley Grassland’ is the Nearctic temperate and subtropical grasslands, savannas, and shrublands ecoregion which was once a diverse grassland containing areas of desert grassland (at the southern end), prairie, savanna, riverside woodland, marsh, several types of seasonal vernal pool and large lakes.

However much of the Central Valley environment has been removed or altered by human activity including the introduction of exotic plants, especially grasses. It is home to California’s most productive agricultural areas. The wetlands have been the target of rescue operations to restore areas nearly destroyed by agriculture

California’s Central Valley is covered by a thick white veil of fog in this image of the western United States of America. This large, flat valley that dominates the central portion of the state stretches approximately 450 miles (720 km) from northwest to southeast, and covers an area of approximately 22,500 square miles (58,000 km2).

The valley is bordered to the east by the Sierra Nevada Mountains, which, true to their name, are capped in snow in this image. Beyond the mountains lies the the Great Basin of the western USA, which  includes valleys, basins, lakes, and mountain ranges of Basin and Range topography.

USA - October 20th, 2011

California’s Central Valley is a large, flat valley that dominates the central portion of the U.S. state of California.

The valley stretches approximately 450 miles (720 km) from northwest to southeast inland and parallel to the Pacific Ocean coast. Here, the coastline is flanked by clouds, a common occurence due to differences in cold ocean water and warm air temperatures.

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.
