Water-filled channels on Mars, illustration. This is the Valles Marineris, which is 4000 kilometres long, up to 200 km wide and up to 7 kilometres deep. Found at the southeastern edge of the Tharsis Bulge, the canyons were originally created by faulting during the formation of Tharsis. Water erosion seems to be involved.
