Fact Sheet
Martian Landslides
Old landslides form curving mounds in Melas Chasma, part of the Valles Marineris canyon system on Mars, in this recent image from the orbiting Mars Odyssey spacecraft. White sand dunes are at the bottom of the picture. Valles Marineris dwarfs Earth's Grand Canyon; it would stretch across almost the entire continental United States. [NASA/JPL/ASU]
