Re: Near Polar Gullies
Great work, Nick -
Now all you have to do is examine the nearby impact craters so you can demonstrate the local sub-surface composition.
I suppose you already know that it is fairly useless to point out to some people that Mars is a big planet with many different types of local mantle structures, and that generalizing from one area to the entire planet is a difficult proposition at best.
My g*d, when I think of the mounds of papers written about wattery Mars in contradiction to the basic laws of physics by people who should know better -
