Nov 18, 2020 at 8:56 comment added David Tonhofer @MarvinKitfox Yes, exactly that Mars. "Depressions" in polar regions are exactly what things tend to. Great tilt gave Mars a new face. No continental drift means things stay that way.
Nov 18, 2020 at 5:08 comment added user79911 @DavidTonhofer You mean similar to Mars, where a) there is no continental drift, and b) the mass imbalance due to the northern hemisphere depression is 75 times the mass of Olympus Mons? That Mars?
Nov 17, 2020 at 22:20 comment added David Tonhofer That's not working. That mountain will move to the equator (i.e. the rotation axis will shift). Similar to Mars, where the big volcanoes are on the equator (but what about continental drift?)

Nov 17, 2020 at 12:06 comment added Hobbamok Nice remembering Mars. Now OPs map is far more extreme (probably), but that could just be that it could be newer, with less time to even out
