Ius Chasma Landslide

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.
In this image, there is evidence of a large landslide. Landslide deposits are common throughout Valles Marineris, but are particularly common here in Ius Chasma.
