Wells Creek is an impact crater located near Cumberland City, Tennessee. It is in diameter and the age is estimated to be (million years old), placing it in the Jurassic or a neighboring period. The crater is exposed to the surface. The center of the crater contains some of the finest shatter cones in the world. Many have been collected and are on display around the world.
The crater contains a central uplift where Cambro-Ordovician rocks of the Wells Creek Dolomite and Knox Group are exposed. These rocks are surrounded by concentric exposures of Ordovician, Silurian, and Devonian rocks. Beyond the uplift are Mississippian rocks of the Chattanooga Shale, Fort Payne Formation, Warsaw Limestone, and St. Louis Limestone. Radial faults are abundant in the central uplift area. Sets of concentric faults surround the central uplift and three rings of them bound the outer structure.
