Mimas' surface, like the surfaces of most of the other major Saturnian moons without atmospheres, is not pure ice but contains some dark impurities; the relatively dark markings appear along the lower portion of the walls of the 130-km-wide Herschel Crater (the peak in the middle of the crater is about as tall as Mount Everest; the impact that made it likely almost destroyed the moon) and some of the smaller craters; scientists interpret this darkening as evidence for the gradual concentration of impurities from evaporating icy materials in areas where the dark impurities slide slowly down the crater wall.
