Persbo (crater)

Persbo Crater is an impact crater in the Elysium quadrangle of Mars located at 8.54° N and 203.24° W. It measures 19.5 kilometer in diameter and was named after Persbo, Sweden.[1] It is just south of the Cerberus Fossae, and is adjacent to the Athabasca Valles, which issue from one of the fossae. 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]
