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

You know, it's really interesting and cool to look into such a Martian pit. But, guys -- it's all basalt. Garden-variety basalt. You can look at the exact same kind of rock all over the Earth, and if you want to get some from off-Earth, there's a quadrillion tons more just 400,000 km away...
In other words, while the feature really looks interesting, it doesn't tell the story about Mars that I want to hear. The rock beds I want to see a sharp cut through are a lot older than this stuff. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
