Hebes Chasma Mosaic (Released 16 September 2004)

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 mosaic shows another part of Hebes Chasma. Sun shadows can be seen on the northern part of the image. There are dunes, flow like features, and layered rocks present.
