Marek Holecek and Radoslav Groh spent nine days climbing their new line on Baruntse. This included four days without food and three days stuck in a tiny tent at 7,000m, while Cyclone Yaas made it impossible to move.
They also endured several miserable bivouacs, notably what Holecek called the Two Butts Bivouac. Here, they spent the night with their legs dangling over the void and constantly sliding down on their steep, icy seats.
The video compilation below gives the flavor of their experience. It even seems to include the Two Butts Bivouac.
