Noctis Labyrinthus (Released 10 September 2003)

At the westernmost end of the enormous Valles Marineris canyon system lies the ruptured landscape known as Noctis Labyrinthus. As the name implies, it is a labyrinth of interconnected canyons that probably results from faulting, collapse, and landslides. The image shows that these canyons are mantled by a thick layer of dust.
