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.
