Mars! It’s a small planet with a lot of big geology.
Olympus Mons is the largest volcano (and tallest mountain) known in our solar system, rising 13.5 miles above its base. Valles Marineris is 2500 miles long canyon system that reaches depths of up to 4 miles, a canyon so vast that the Grand Canyon would fit into one of its side canyons. There are the dry valleys and deltas of ancient river systems that once flowed to a shallow sea in the north polar region. Towering dust devils and vast dune fields sculpted by their tenuous atmosphere, all this and more.
