Changing Planet
A perspective view of a mesa in the chaotic regions east of the Valles Marineris, reveals a surface that collapsed a long time ago, when large volumes of liquid, perhaps water, were removed in the subsurface and flowed towards the northern lowlands of Mars. The large crater in the background has a diameter of 7.6 km and a depth of 800 m.
