In a sense, the ice channels of the Aletsch Glacier are mother nature’s luge track. These meltwater veins cut meters into the ice to form smooth pathways down the glacier. With the expertise of his guides, David Carlier was able to ride the meltwater to photograph this unique winter sports experience. From high above and deep within these channels of ice, Carlier has captured a dream of many outdoor adventure enthusiasts. The expertise of Carlier’s guides is important to mention. Both Claude-Alain Gailland and Gilles Janin have plenty of experience scaling the Aletsch Glacier. They outfitted their expedition with solid headgear, lightweight luge boards and finned footwear to help navigate the ice channels. These channels often fork off in different directions, and there are occasional hurdles to overcome. This gear keeps the trio safe and allows them to navigate the meltwater as they descend the glacier. – – – David Carlier is an award-winning adventure photographer based in Switzerland.
