Ceraunius Tholus

High sloped volcanic dome on Mars. Clouds were found over its summit. The sides are etched with valleys, suggesting a soft easily eroded material was deposited, such as ash. One of them leads into the nearby Rahe crater. The larger neighbor of the similar Uranius Tholus. The summit may have held an ice cap and or a lake at one point.
