My question(s):
That sounds like Hell on Mars, Nick! What a spectacle it would have been! What kind of time frame would you postulate for the channel formation? And where did all that huge volume of CO2 come from? What was it doing before the outburst? Would there be any kind of CO2 cycle to provide longer-term flow?

I'd always assumed from your unabashed support of Nick's thesis that you were familiar with the details of his model, so forgive me for asking: Have you in fact read any of Nick's material about White Mars? If not, try

where I believe most (if not all) of your questions will be answered. Needless to say, although I find some aspects of White Mars interesting, I do not accept it at this time.
