I wonder if the color changes on the surface are a grain-size phenomenon? Fine coating --> lumpy bigger grained avalanche debris
or grains on the surface slowly subliming-redepositing to get bigger grains, then getting ground down to dust during the avalanche event? (initial Fine coating --> bigger recrystallized grains --> avalanche dust). Hyperion also has the same kinda look. Anyone know if VIMS also got images? -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
