PIA14680 with the false color portion overlaid and the details enhanced using a hipass filter of the grayscale image. This help correlate the surface false color image with surface features:
Those orange pools north (?) of the crater look really, really interesting. If I got the spectral assignments correct they are lacking in green, thus iron-poor. (Green = small ratio of 750 nm to 900 nm, large reflectance at 900 nm, thus not much iron since iron absorbs at 900 nm). Did some deep iron poor stuff get blown out of the big deep crater, then more deep iron poor stuff ooze up and out? The E-W (?) streakiness also doesn't seem to be an artifact. EDIT: Yup! Those orange pools seem to filling local basins. Check out a more oblique angle image here (this thread): -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
