Three amateur climbers take on the challenge of scaling an icefall in the High Tatras mountains of northern Slovakia and film themselves doing it in this spine-tingling video.
First they prep themselves with ropes and pickaxes while standing at the bottom of their quest: essentially a vertically-inclined mountain of what appears to be sheer ice.
As they start the climb, it gets difficult almost immediately. There's a lot of hammering and clawing, and breathless grunts as they toil their way up the thick, icy slope.
According to the videographer, the ice turned out to be about four to five meters thick in most places. Watch the video to see if these ice-climbers were successful in their quest.
