A Scottish woman mountaineer watched helplessly as her climbing guide fell to his death on New Zealand's highest peak, 3,754-metre Mount Cook in the Southern Alps, news reports said Wednesday according to DPA. The pair were about 350 metres from the summit on Tuesday when a lump of ice came loose and the 54-year-old guide fell 60 metres, receiving fatal head injuries. The guide, whose name was not immediately released, had climbed past the woman to secure their ropes to an anchor when he fell, Ross Campbell, of the Department of Conservation, told the Dominion Post.
