Re: Timing is everything
Valles Marineris might be a deep canyon system, but it's set in elevated terrain. If you want to go deep to look for water, you;re better off looking in Hellas, which, IIRC is the deepest crate on the planet. I'd love to see what the base of the walls of Hellas look like close up. And test the soil for brines at the deepest point.
