The Sutter Buttes, are a unique cluster of volcanoes located a few miles to the north west of Yuba City. Thrust up through the valley floor approximately 1.5 million years ago, the multi-crested mountain range was an inland island during the era when the northern valley flooded and was revered by the areas, once prevalent, Maidu Indians. Often called the smallest mountain range in the world, the Maidu Indians called them Esto Yamani (Histum Yuani) which translates to The Middle Mountain.

The Middle Mountain Foundation, MMF, is a non profit organization that strives to educate the general public about the  importance of  natural and cultural resources and to encourage preservation, understanding, and good stewardship of such resources. 

Through contractual agreements with landowners, MMF has created learning opportunities within the Sutter Buttes for thousands of people, typically as guided hikes for the public. Carefully controlled access allows visitors to have high quality experiences while protecting the land itself.

The Middle Mountain Foundation Interpretive Program hikes provide access to the beautiful, privately owned hillsides and peaks.

Sutter Buttes hikes are scheduled through the Middle Mountain Foundation, (530) 671-6116, www.middlemountain.org. Most hikes cost $35 and some sell out quickly.  The fall hike schedule will be posted on the MMF website on October 7th.  You can charter a customized private hike for up to 10 people for a fee of $300; add $30 for each additional person.  The diverse outings include climbs to high canyon ridges, moonlight strolls, geology, birding and native culture treks, plus one devoted to bat research. They span a range of difficulty from strenuous summit ascents to simple wildflower rambles. Most hikes are not suitable for children, so inquire in advance.

The organization has always favored inclusiveness, bringing together private landowners with scientists, educators, students, families, artists, and other citizens. The common ground is the Sutter Buttes itself and the natural and cultural history they hold.

To explore the extinct volcano's 10-mile circumference by car, take the 45-mile loop of county roads that circles them (from Highway 20 take Acacia Ave to Pass Road).  Explore this special place either by foot on a MMF hike (the entire area, excluding county roads, is privately owned and not accessible to the general public) or by car and experience a close up view of the smallest mountain range in the world.
