Tharsis Montes
Tharsis Montes At far left are the small Uranius Tholus and the conical Ceraunius Tholus, close together. Then, from left to right (northeast to southwest) are the three Tharsis Montes: Ascraeus, Pavonis, and Arsia Mons. Arsia has a bit of early morning cloud to the southwest of its peak.
