Devil's Tower

The mysterious Tower of the Devil, known as Devils Tower, is located in northeastern Wyoming in the United States. Its height is over 1,266 ft., which is comparable with the height of the Empire State Building, which is about 1,250 ft. without the spire. The rock formed about 65 million years ago by volcanic activity, and is unusually shaped in the form of woman's hips which was the result of erosion of the surrounding soft rock around a strong internal structure.
