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] 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]

Persbo Crater Foor, as seen by HiRISE. Scale bar is 500 meters long. Impacts into floor reached a layer of light-toned materials. These materials were then thrown out over a slightly darker surface. Light-toned materials may be hydrated minerals like sulfate.
