Cemented Fractures in the Mountain inside Gale Crater (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)

One type of feature of scientific interest on the mountain inside Gale Crater is exposure of Cemented Fractures, evidence that groundwater once reached to at least that height of the Mountain.

This image of that part of the mountain, taken by the High Resolution Imaging Science Experiment camera on NASA's Mars Reconnaissance Orbiter, shows symmetry in how material on one side of each fracture is balanced by material on the other side. This pattern indicates that mineral-saturated groundwater once filled the fractures. The water deposited minerals on both sides of the opening, eventually filling the gap.
