Ius Chasma Debris

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 collected during the southern spring season. Debris from a landslide appears to cover most of the scene.
