Here's a crater - middle of this view - with dark markings inside and outside its rim. Other distant images show at least one other dark spot like this as well.

Here's a crater - middle of this view - with dark markings inside and outside its rim. Other distant images show at least one other dark spot like this as well. Tried to line up the IR image with this view. If I got it right, that crater is right in the middle of a "greenish" splatty zone. This is the same tint as the sharp scarp face. There are two other greenish splatty zones below the central peak in the image, but I'm almost positive this area is misregistered. I'm going to run with the idea that the green tint indicates fresher material. -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
