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.[1]
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.[2] The peak is caused by a rebound of the crater floor following the impact.[3]
