Water way to go. These incredible images show the moment two brave adventurers decided to body board down Europes longest glacier. Seen carving their way through the icy rivers of the Aletsch Glacier in Switzerland, the pair are seen risking their lives for an adrenalin rush of a whole new kind. Pictured mounted on their body boards as part of a sport known as hydrospeeding, the daredevils risked being carried away by strong currents and even drowning in hidden crevices to complete the winding seven mile journey. But if that wasnt dangerous enough, the duo also ran the risk of being overwhelmed by collapsing glacial lakes that could be released into the river at any moment. Luckily, Swiss mountain guide, Claude-Alain Gailland and canyon activity specialist, Gilles Janin, are part of only a handful people in the world qualified enough to perform the treacherous run. Located on a UNESCO world heritage site, mountaineering photographer, David Carlier, 42, spent five hours trudging through the icy terrain to reach the summit of the colossal ice mass.
