Realistic perspective views of the surface of Mars can be generated from data acquired by the stereo and colour channels of the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, which are oriented at an oblique angle with respect to the planet's surface. This view from the southwest shows the mouth of Ladon Valles (foreground), from which large quantities of water flowed onto a low-lying plain, depositing layers of sediment. Near the boundary of the outflow, bright material can be seen that is thought to consist of minerals that formed in either standing or flowing water. In the background, the two overlapping craters Shambe (left, diameter 35 kilometres) and Sigli (30 kilometres) also have sediments deposited on their floors.
