Sutter Buttes

The Sutter Buttes form a circular complex of eroded volcanic domes rising 2,122 feet (647 m) above the Sacramento Valley plains and represent the smallest mountain range in North America. The structure consists of overlapping volcanic cones concentrated in a single location.

These volcanic cones formed during the early Pleistocene period, about 1.6 million years ago, through a series of eruptions spanning roughly 200,000 years. No volcanic activity has occurred at the site since that distant past.

The Nisenan, Maidu, and Wintun peoples used these mountains as seasonal gathering places and wove them into their creation stories. The landscape held deep spiritual significance for the communities who lived nearby.

Access is only available through authorized guided tours, as most of the land is privately owned by local farmers. Visitors must arrange in advance and follow established access procedures.

Between 1960 and 1965, the United States Air Force operated a Titan intercontinental ballistic missile launch site on the northern side. The facility was decommissioned and left no visible traces.
