Sutter Buttes
The Sutter Buttes (Maidu: Histum Yani or Esto Yamani, Wintun: Olonai-Tol, Nisenan: Estom Yanim) are a small circular complex of eroded volcanic lava domes which rise as buttes above the flat plains of the Sacramento Valley in Sutter County, northern California. They are situated just outside Yuba City in the northern part of the state's Central Valley.
