Big wall climbing

The big wall climbing (german big wall " great wall " ) referred to in mountaineering and climbing, the climbing the tower by high rock walls that can not be climbed in a day normally, so that must be the go bivouacked.

The big wall climbing was in Yosemite Valley (USA), where numerous high and steep granite walls require bivouacs, for which there is sometimes no suitable ledges or tapes. Therefore, so-called portaledges have been developed to a certain extent tents with a sturdy base that can be hung on a hook at its tip. These will then slept hanging under circumstances hundreds of meters above the ground. All supplies, even water for the entire tour and the extensive climbing equipment be taken and redrawn each after climbing a rope length in a sack.

Big wall routes are generally partially committed in technical climbing, because free climbing is often not possible or would be very time consuming.
