Interesting new image of the Arsia Mons pit. The polar pit gullies image is pretty good, too. |

Unfortunately, most of the pits which may lead into lava tubes are located on the flanks of Tharsis volcanic piles, which are located significantly higher than median. Even if these "caverns" bottomed out a km below the local surface, they would be higher above the median than, say, is the floor of Hellas. So, unless there is some other mechanism concentrating the atmosphere, I can't see how it would be significantly higher in pressure down in these tubes than we see at, say, Meridiani.
