Mars rarely impresses me lately, though I have to admit, HiRISE has taken some pretty nice images. This one impressed me:

Caught in Action: Avalanches on North Polar Scarps

This image shows dust clouds resulting from avalanches along cliffs near the north polar cap. Very cool stuff. I wonder what the trigger mechanism is since there appear to be several avalanches going off at the same time.
