Where Ophir Meets Candor

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 bordering areas between Ophir Chasma (northern half) and Candor Chasma (southern half). Wind etched surfaces and dunes are present on the floor of Ophir Chasma.
