Old Landslide In Ius Chasma

THEMIS has taken some great pictures of Valles Marineris, the largest canyon in the solar system. If this canyon were on Earth, it would stretch from New York to Los Angeles. Image of the Day toured some of the canyons that make up this vast system.
This image of Ius Chasma was taken during the southern summer season. An old landslide deposit is visible to the right of the image, coming off the northern wall of the canyon.
