1 comment on en.wikipedia.org/wiki/Valles_Marineris

#Valles_Marineris (Latin for Mariner Valleys), is a system of canyons that runs along the #Martian surface east of the Tharsis region. At more than 4,000 km (2,500 mi) long, 200 km (120 mi) wide and up to 7 km (23,000 ft) deep,[1][2] the Valles Marineris rift system is one of the larger canyons of the #Solar_System, surpassed only by the rift valleys of Earth and (in length only) by Baltis Vallis on Venus.
