Sudden roar
Those two members of mountaineering service of Montenegro were surprised at the top of 150 meters frozen waterfall. At the bottom ice was nice and thick, but only from above it was clear that the top of the last 50 meter section was melted. Thanks to their experience they summited after 4 hours, but they claimed that it was scariest thing they have ever done!
