Montevallo is a crater on Mars, located in the Lunae Palus quadrangle at 15.4° N and 54.4° W. It measures 51.9 kilometers in diameter and was named after the town Montevallo in Alabama, United States. The name was approved by IAU's Working Group for Planetary System Nomenclature in 1988.
Impact craters generally have a rim with ejecta around them, in contrast volcanic craters usually do not have a rim or ejecta deposits. As craters get larger (greater than 10 km in diameter) they usually have a central peak. The peak is caused by a rebound of the crater floor following the impact.
