The origins of riverboards (known as hydrospeeds in Europe) are as murky as the water of the rivers they are running. But one thing is for sure: there's few crazier ways to run a river. Of course, it takes a certain kind of crazy to find this sport appealing – just ask the guy who riverboarded 2,000km.
Above, photographer David Carlier and friends decide to take riverboarding to rarely-touched water – a free-flowing river (or moulin) in the 14km-long Aletsch Glacier. It's the biggest glacier in Europe, and yes, that water is cold – all year long.
