Candor Chasma Rim

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 shows the northern rim of Candor Chasma. Dunes and wind-shaped surfaces are very common in this area.
