Fort Rock is a tuff ring located on an ice age lake bed in north Lake County, Oregon. The ring is about 4,460 feet in diameter and stands about 200 feet high above the surrounding plain. Its name is derived from the tall, straight sides that resemble the palisades of a fort. The region around Fort Rock contains about 40 such tuff rings and is located in the Brothers Fault Zone of central Oregon's Great Basin. William Sullivan, an early settler in the area, named Fort Rock in 1873 while searching for lost cattle. Fort Rock was created when basalt magma rose to the surface and encountered the wet mud of a lake bottom.
Like a desert mirage, this National Natural Landmark rises out of the barren, immense flatness of Oregon's high desert. An enormous near-circle of towering jagged rock walls make it look like a fort. Hike around and you'll soon realize it's even bigger than it looks! It's an old tuff ring set in what was a shallow sea in prehistoric times.

The town of Fort Rock had a general store which also included a gas station that was in operation from the early 1900s until it closed in May 2013.
