Description: Valles Marineris
It is a vast canyon system that runs along the Martian equator. At 4,500 km long, 200 km wide and 11 km deep, the Valles Marineris rift system is ten times longer, seven times wider and seven times deeper than the Grand Canyon of Arizona, making it the largest known crevice in the solar system.
