The dome is about 10 miles in diameter. The possibility is suggested that this could have been picked up from the formerly overlying New Albany, or Chattanooga, shale (Brown 1954). The roughly circular dome has prominent topographic expression on aerial photos and satellite images. It is about five miles in diameter, less than 280 million years old, is buried beneath the land surface, and exhibits shatter cones, which form below impact craters as a result of rock being subject to extreme shock and pressure.
