I wonder? If the floor of the Valles Marineris Canyon on Mars would have water, 
oxygen, gravity more like Earths. Do you think, considering the size of Mars, 
that a deep canyon might support life, better than the surface? Would it be 
warmer if it's closer to the center of Mars? I understand on the surface water 
evaporates, how about down under?
