Perspective view of a mountain in the eastern Hellas region of Mars surrounded by a lobate deposit with flow textures on the surface. Recent measurements from the Mars Reconnaissance Orbiter SHARAD radar sounder have detected large amounts of water ice in similar deposits, arguing for the flow of glacial-like structures on Mars in the relatively recent geologic past. This suggests that snow and ice accumulated on the slope face and flowed viscously over the neighboring plains and is now protected from sublimation by a layer of rock debris and dust.
