The Sutter Buttes are a small circular complex of eroded volcanic lava domes which rise as buttes above the flat plains of the Central Valley of California in the United States. 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. They are named for John Sutter, who received a large land grant from the Mexican government. The Sutter Buttes are sometimes referred to as the world`s smallest mountain range.
