This large Moulin was the last one we explored on this trip. This was located on one of the side glaciers as it joined the Gornergratz glacier.
Martin is about halfway down at this point. Water flows off to the right of the picture in a rift. Picture shows a change in the ice from the freeze/thaw shattered upper layers to hard. Compact and clear ice lower down.
Martin also had further adventures in the glacier on a return trip in October 2011 - good write up by one of the participants, Henry, here.
