I gaze at these photos in sheer awe of nature. These are from http://www.coolantarctica.com/ It's quite a humbling experience standing close to an ice berg the size of an office block, particularly when you consider that the bit beneath the thin sheet of ice you're standing on is the size of 8 or 9 office blocks. The whole scale of Antarctica is really quite awesome, such moments and places serve to remind us that we are really quite insignificant to the motions of the planet. These motions that took place before we "discovered" them, continue oblivious to our presence and will still continue when we are no longer around to see them. The cold winter temperatures usually mean crystal clear days as there is no water vapour in the air. The scale of Antarctica in these conditions becomes quite overpowering, almost frightening. You can be standing on a cliff edge and be able to see a clear 100 miles in all directions knowing that the only other human beings in that 100 mile radius circle are your fellow winterers in the collection of huts just below you. If the air is still then the silence too is equally huge, with nothing moving or making a sound in the whole of that vast wilderness.
