Gledhill is an impact crater in the Hellas quadrangle of Mars, located at 53.2°S latitude and 87.1°E longitude. It is 78.5 km in diameter. It was named after British astronomer Joseph Gledhill, and the name was approved in 1973 by the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (WGPSN).[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] Gledhill Crater shows a central peak in a picture on this page.
