Agriculture in California’s Central Valley, USA – November 26th, 2012

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.

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.

Rising up above the agricultural areas and flat plains of the Sacramento Valley, which stretches between the Coastal Mountains (left) and the Cascade Mountains (right) in this orthorectified image, are the Sutter Buttes.

The Sutter Buttes are a small circular complex of eroded volcanic lava domes. The highest peak, South Butte, reaches about 2,130 feet (650 m) above sea level. The Buttes are located just outside of Yuba City, California in the Sacramento Valley, the northern part of the Central Valley.

The mountains are about 10 miles (16 km) from north to south and east to west, and are the smallest mountain range in the world. They were formed over 1.5 million years ago by a now-extinct volcano.

The Sacramento Valley stretches between the Coastal Mountains (left) and the Cascade Mountains (right) in California, USA.

Here, the Coastal Mountains include the peak known as Pence Mountain, a summit in Colusa County that climbs to 1,857 feet (566.01 meters) above sea level.

The Cascades, on the other hand, include a peak called Promontory Point, a summit in Tehama County that reaches  3,589 feet (1,093.93 meters) above sea level.

A small, seemingly out-of-place peak can also be seen in the middle of the valley, at the bottom of this  orthorectified image. These are the Twin Peaks, comprised of North Butte and South Butte, part of the Sutter Buttes.

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.
