Valles Marineris

The Valles Marineris, or Mariner Valley is named after The Mariner space probe which first photographed its features.It is located just south of the Martian equator. It is a system of canyons, about 4000 km long, and, if on earth, would extend all the way across the United States. The main central canyons are about 50 to 100 km wide, with a large depression as much as 600 km wide. In the deepest places the canyon floor reaches a depth of 10 km, nearly 7 times deeper than the Grand Canyon.
