Looking from an imaginary point above the surrounding highlands in the middle of the Valles Marineris looking south to north. You can see the three parallel valleys Melas Chasma, Candor Chasma and Ophir Chasma, each about 200 km wide. The steep cliffs in the background and centre are about five metres high and show traces of intense erosion. At the foot of the mountainface the remains of massive landslides can be seen. How this enormous structure on the surface of Mars was formed, is still unclear. The topography shown is twice as high as in reality. Perspective colour view.
