Santa Fe is an impact crater in the Lunae Palus quadrangle of Mars, located at 19.5° North and 48.0° W. It is 20.5 km in diameter and was named after Santa Fe, New Mexico, USA.[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]
