"Are Martian Gullies Generated by Granular Flows?" by Dr. Troy Shinbrot of Rutgers University.

An Associate Professor of Biomedical Engineering at the New Jersey institution, Shinbrot's regular area of study is how various pharmaceutical products flow and interact with each other.

At a conference he co-organized with Cornell Professor Michel Louge in 2002, Shinbrot was discussing the "beautiful pictures" he saw of the Martian gullies. To Shinbrot, these surface features looked like they were made by the sandy particles themselves moving down the sides of banks, canyons, and craters, and not by liquid water.

...

From his previous granular flow research, Shinbrot knew that very light particles in a lower gravity environment act like a liquid before they eventually settle together to behave as regular solids.

--------------------
"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

Alex had some interesting answers to my points, which I won't insert here without permission.

No problem, John. Go ahead. If I don't like it, I can always plead lack of memory (à la Moomaw). tongue.gif
