Catalan kayaker Aniol Serrasolses navigated a river atop the Bråsvellbreen glacier on the Arctic island of Svalbard.
After a 36-hour sea voyage from Longyearbyen and an 11km hike through the glacier, the 32-year-old adventurer paddled through rapids and ice tunnels on the ice cap before descending a 20-year-old icefall. 20m.
A feat considered the greatest glacial waterfall descent ever recorded.
