In this image, we see an approximately 500-meter crater that is fairly fresh (in geological terms), but the ejecta is already high-standing. Could this be an indication of early stage of pedestal development?
A pedestal crater is when the ejecta from an impact settles around the new crater and is more erosion-resistant than the surrounding terrain. Over time, the surrounding terrain erodes much faster than the ejecta; in fact, some pedestal craters are measured to be hundreds of meters above the surrounding area. [More at link]
