Theophilus (center of first frame) is one of the most prominent ring mountains with a considerable terraced interior wall. It is 100 km in diameter, and has a depth of 4400 m. The ridge of the wall rises 1200 m above the surrounding terrain. A group of central mountains rises to about 1400 m above the floor. The wall of Theophilus interrupts that of neighboring Cyrillus, proving that the former is the younger formation.
