Valles Marineris

Valles Marineris

The Grand Canyon of Mars is Valles Marineris, but it is much grander than the one on Earth. It is ten times wider than Earth's Grand Canyon, and it would stretch across the entire United States! It is also 7,500 meters deep–almost as deep as Mount Everest is tall! (Planet features are named in Latin. In English, it would be ''Mariner Valley'')
