Here’s a starting point for those calcs: http://www.mide.com/pages/air-pressure-at-altitude-calculator I’m thinking about half that, plugging in an altitude of -8000 into the second calculator. Calculate Air Pressure at Altitude Pressure at Sea Level 32000 Temperature 15 C Altitude -8000 Air Pressure at Altitude = 76532 You’ll have to play around with temps and this is based on a 1G planet but they have a mars calculator as well; but Canyon wasn’t as cold as mars, IIRC. > On Oct 16, 2016, at 5:00 PM, Christopher Sean Hilton <xxxxxx@vindaloo.com> wrote: > > Valles Marineris on Mars is 8km deep.
