Olympus Mons is about 600 km in diameter and the summit caldera is 22 km above the surrounding plains. The summit caldera (central depression) is almost 3 km deep and 25 km across. It probably formed from recurrent collapse following drainage of magma resulting from flank eruptions. Image taken from Mars Express spacecraft on august 29 2023.
