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.

This image of the western United States of America shows a varied geography, ranging from desert to mountainous to fertile valleys.

The fertile green of the states of Washington, Oregon and California (from top to bottom) can be seen along the western shores. Parallel to the coast, in the lower half of the image, is California’s Central Valley, an area of great agricultural production.

Over the Sierra Nevada, further east, is the Great Basin, the largest area of contiguous endorheic watersheds in North America. In spite of this, it is noted for its arid conditions and Basin and Range topography, and spans several deserts.

USA - July 25th, 2011

The fertile green of the western coastal states of Washington, Oregon and California (from top to bottom) is striking in comparison to the more arid terrain of the Great Basin further inland. Parallel to the coast, nestled between mountain ranges is California’s Central Valley, an area of great agricultural production.

The Great Basin is the largest area of contiguous endorheic watersheds in North America and is noted for its arid conditions and Basin and Range topography. The region spans several physiographic divisions, biomes/ecoregions, and deserts. The large white expanse near the right edge of the image are the Bonneville Salt Flats, just west of the Great Salt Lake, in the state of Utah.

Central Valley, also known as the Great Central Valley, is located in California, USA. Extending from Shasta county in the north to Kern county in the south, it covers about 18,000 square miles (47,000 square km) and parallels the Pacific coast for about 450 miles (725 km).

Averaging about 40 miles (65 km) in width, it is almost totally enclosed by mountains, including the Klamath Mountains (north), Sierra Nevada (east), Tehachapi Mountains (south), and Pacific Coast Ranges (west). The Sacramento and San Joaquin rivers, which run through the Central Valley, are fed mainly by the abundant rains and melting snows of the Sierra Nevada.

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.
