Some pretty complex driving by the look of it:

Sorry this is long, but I found myself on a roll...
It definitely seems to be a "crusty unit," but going so far as to call it a "duricrust" seems unwarranted. I really haven't yet seen anything I'd call a true duricrust on Mars. I really prefer the "weakly cemented by salts" hypothesis. Water ice is a second choice for me. There were a few images from around sol 110 taken near Endurance that keep popping up as examples of duricrust, but taken in the context of the surroundings, they appear to me to be soil/dust covered slabs of fractured bedrock that were disturbed by Oppy's wheels. Purported examples of duricrust: http://marsrovers.jpl.nasa.gov/gallery/all...03P2584L7M1.JPG http://www.lyle.org/~markoff/pds/234567/1P...87L234567C1.JPG Context images showing the dust/soil covered plates of broken-up bedrock surrounding Endurance crater: http://marsrovers.jpl.nasa.gov/gallery/all...3P2366L7M1.HTML http://marsrovers.jpl.nasa.gov/gallery/all...3P2366L7M1.HTML http://www.lyle.org/~markoff/pds/257/1P137...P2361L257C1.JPG These are some that have been partially exhumed: http://www.lyle.org/~markoff/pds/257/1P138...P2295L257C1.JPG http://www.lyle.org/~markoff/pds/257/1P138...P2295L257C1.JPG -------------------- ...Tom
