Snakeweed and rabbitbush growing around Fort Rock State Natural Area, a volcanic landmark called a tuff ring, located on an Ice age lake bed in north Lake County, Oregon, United States. It is about 1/3 of a mile in diameter. Its tall, straight sides resemble the palisades of fort, thus giving the rock its name. This region contains about 40 such tuff rings and maars and is located in the Brothers Fault Zone of central Oregon's Great Basin.
