Whitney. Wonder what the pressure gradient would be from the bottom of Valles Marinaris and the mean surface of Mars?

Any human "pod" or capsule would be subject to extreme heating and cooling, expansion of gases and sublimation of CO2. An interesting place to model!

The great explorers all seem to look at things slightly differently than the rest of us. A tourists view would probably be from the top looking down , while an explorer would be looking from the bottom up. At the very least, it would be a magnificent view either way.

If it were, might be a good place to put a manned base of some type. I wonder if the atmospheric pressure is significantly greater at the bottom of the chasm.

The Grand Canyon is a water erosion formation. Valles Marinaris is a rift. Quite different. "Jeff Says:

A lander (or climber) alone wouldn't be as handy to survey all that stuff. To get a REAL good look, you'd
