I jumped into a seal hole, pushing the ice away as I entered, and they handed me my camera. Surprisingly, I wasn't too cold, except around where my mouth held on to my regulator, and that instantly froze and became numb. Suddenly everything was quiet and I found myself looking at easily one of the most extraordinary scenes I had ever, ever experienced. When I dropped down through a hole in the ice, I was completely surrounded by ice: a tunnel maybe twenty feet across. Everything above me on the land was roaring with wind and down there, there was absolutely no sound except for the distant trills of Weddell seals.
