Interesting new image of the Arsia Mons pit.

The polar pit gullies image is pretty good, too.

Oh, trust me, I'd be first in line if they were asking for volunteers to go spelunking down into that hole. As far as sense of wonder, and also human-habitable volumes, are concerned, the place is a wonder. And I don't write it off as being *completely* uninteresting from a geological point of view.

But, hey -- if Steve Squyres can write about (paraphrasing here) "nothing but boring, uninteresting chunks of lava as far as the eye can see" about the floor of Gusev, I figure I've at least a little support for the idea that the real action truly is in the much older rocks.

I do admit, though, that Martian caverns would be the perfect places for medium-term and long-term human habitats. Their interiors are protected from solar and cosmic radiation (a very important consideration), and the application of enough heat (plus a little Yankee building ingenuity) could seal up cavern walls and allow a section of a cavern to be pressurized with a livable atmosphere. Heck, with enough native water, you might even be able to make indigenous concrete...
