The Hydraotes basin has a diameter of 420 kilometres. This oblique view, which was derived from image data acquired by the HRSC stereo channels, shows the structure of the numerous mesas, buttes and hills that resisted the erosive power of flowing water and today tower above the base of the valley. At the foot of some mesas, terraces and the remains of landslides are visible. In the background, the beginning of the Simud Valles outflow channel is visible.
