pedestal crater

Pedestal craters are a distinctive geological feature found on Mars. They are impact craters surrounded by a raised platform, or pedestal, formed from the ejected material. This pedestal protects the underlying ground from wind erosion, causing the surrounding terrain to be carved away while the ejecta remains intact.1

The formation of pedestal craters suggests that erosion rates on early Mars were significantly higher than they are today. The presence of these craters, along with other eroded features like valleys and channels, indicates that Mars once had a different climate, possibly one with flowing water.1

Impact craters in general, including those on Mars, are formed when large meteoroids strike a planet's surface at high velocities. These impacts release immense kinetic energy, creating craters. The size and preservation of craters can provide clues about the age of a planetary surface and the history of bombardment in the solar system.12
