Pulling yourself up a wall of ice using just ice picks and crampons is both dangerous and difficult. Graham and Ed find out just how difficult as they travel to the Exploradores Glacier in Chile and attempt to climb a 125ft glacier wall. Newsreader Fiona Bruce then finds out just what it takes for the average holiday skier to tackle one of the longest and most challenging glaciers in the world, the Jungfraujoch in Switerland. Graham and Ed help Fiona down one of the most famous one-day tours in the world - 24km of unbroken glacier descent.
