Left image: Seeping features on the walls of a valley located in the high latitudes of Mars. The channels are fresh and their alluvial fans are deposited on the top of young dune fields. These features are suspected to be currently active. They would be the first evidence of water on present day Mars. MOC image.Middle image: Seeping features on the walls of an impact crater also located in the high latitudes of Mars. The morphology is typical for seepage channels. It shows a source-area characterized by an alcove-like morphology, channels and sediment deposited on the slope. These features are also suspected to be active currently. Right image: Ceraunius Tholus. The slopes of this volcano presents the highest density of recent (Amazonian) runoffs on Mars. It is believed that these runoffs were formed by hydrothermal activity.
