Arsia Mons! One of Mars’ largest volcanos, and part of an arc of three known collectively as the Tharsis Montes. The volcano to the top right is Pavonis Mons, and further beyond (past the visible horizon) is Ascraeus Mons. The much more famous Olympus Mons is also found in the same region, to the northeast of the Tharsis Montes (which would be towards the bottom right in this particular image).
Interestingly, that massive cloud formation is a yearly phenomenon that happens right before the start of winter. The size of the cloud trail varies from year to year, but it’s not uncommon for it to stretch more than 1000 kilometers.
