Climbers in the Czech Republic are scaling a treacherous wall of ice, just because they can. As temperatures in the country dropped well below zero, members of the Czech Climbing Union decided to make their own fun. They pumped water over the face of a 130-foot cliff in the Moravian town of Vir. It took about five days for the water to freeze. And once it did, it created a new challenge for the daring, who used picks, crampons and ropes to reach the summit.
