This observation shows a tongue-shaped flow of material below a scarp in Phlegra Montes, a range of curving mountains and ridges on Mars.
This type of feature is sometimes formed by a debris flow, a landslide, or the flow of ice-rich material. However, the source of the material and how it was deposited here remains unclear.
