GLACIER ICE CLIMBING

COURAGEOUS climbers descend 400 metres as they manoeuvre their way through thick walls of ice. The ice emits a blue glow as the climbers make their way down and move through the glacier. The stunning photographs were captured by American glacier trekking guide Jared Carlson on a trip to the Mendenhall Glacier in Juneau, Alaska. The 36-year-old was joined by climbing friend Jason Nelson, 37, as the pair explored the moulin, which is a circular, vertical well-like shaft within a glacier.
