Grand Canyon vs Mariner Valley.

damn this makes the grand canyon look like a stupid piece of shit

every geological structure on mars makes the earth equivalent look like stupid pieces of shit

if i remember anything from my astronomy class a year ago, its because mars is slightly smaller than earth, so the lower gravity allows more movement of the tectonic plates which creates more dramatic mountains, volcanoes, canyons, etc
