Can comets create a microclimate crater on Mars 30km deep with 0.7bars?

[QUOTE="Vanadium 50, post: 6840280, member: 110252"] Alternatively, there are three kinds of medical treatments: diagnostic, therapeutic and punitive. The OP asked a question, which took us a little while to puzzle out. He got an answer, which he didn't like. Now it's science fiction? I did look up the craters in the solar system. I was unable to find a single one as deep as the OP wants. That includes Mimas, which has one that nearly destroyed it, and the southern half of Vesta, which arguably did. You can buy a piece of Vesra through the mail these days. I strongly suspect that there is no process that will make a hole like this without collapse. (Just as you can't pile rocks up arbitrarily high) Now, Niven did invent a world, "Canyon" that was sort of like this (and I deserve a reward for re-railing this thread) but Niven's science was straight outy of the 60's and even so wasn't always 100% right. But [I]Canyon[/I]!" is a poor rebuttal to "this won't work on Mars." [/QUOTE]
