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... -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
