Of course we've seen similar side by side images showing the changes between the years. I never get tired of them...

Here's a couple...from 06/05/2000 M1600291 12.02m/pixel and 08/16/2005 S0901626 3.21m/pixel

I rotated M1600291 so it would line up with S0901626. I didn't really scale them efficiently, M1600291 appears at 2x while S0901626 appears at 0.5x

You can see that a couple of the 'seeps' (dust slides or whatever) are new. The other section I enlarge 2x from S0901626 I thought interesting as the 'dust' passed over two outcroppings but only made them slightly darker while the rest of the trail is quite a bit darker...I would think the darkness would be more uniform...maybe the dust didn't stick to the outcrop so much?

Some interesting gullies from MGS:

--------------------
"After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance.
I see that such intercourse long continued would make one thoroughly prosaic, hard,
and coarse. But the longest intercourse with Nature, though in her rudest moods, does
not thus harden and make coarse. A hard, sensible man whom we liken to a rock is
indeed much harder than a rock. From hard, coarse, insensible men with whom I have
no sympathy, I go to commune with the rocks, whose hearts are comparatively soft."

- Henry David Thoreau, November 15, 1853
