We discovered this huge hole in the Glace De Mer. Deep, dark, cold and noisy. Absolutely mad environment to climb in.

I remember seeing a moulin much smaller than this in '08, I don't recall any others so if its the same one then its become bloody big! How deep did it go?

Didn't know they were called that! No idea how deep it was as it went pitch black not far below the climber in the photo..I wouldn't be that suprised if it went down to the bedrock.

I've heard that it goes all the way down to the earth's core!!!
