About Valles Marineris

Valles Marineris runs about 3,800 km (2,400 mi) along the Martian equator, long enough to stretch from California to New York and more than ten times the length of Earth's Grand Canyon. NASA puts its deepest point about 9 km (5.8 mi) below the rim.

This print frames its widest part, where Ophir, Candor and Melas Chasmata lie side by side. ESA measures each trough at about 200 km (120 mi) wide and 5 to 7 km (16,000 to 23,000 ft) deep. The canyon system is named for the science team of the Mariner 9 mission.
