Now above the Oildrum Glacier is an Water course that freezes each year, Its in the shadows in the above photo (important), I've blown it up below off a different angle.
You can see the bottom half is well whited up; this is a forty five degree slab, above it the water runs over blocky ledges and often mushrooms in winter, It looks a little lean in this piccy.
Of course Its all thawed now, but it does seem the right time of year to giveaway a winter project, and I'm sure it'll return.
Enjoy
