A-Kuo is correct.
Big wall rock climbing had been developed into a special style of rock climbing originated from Yosemite. Special equipments are also developed for its need; such as haul bag, portaledge, bolt kit, and static rope haul line etc.
Pushing the big wall rock climbing to an even more extreme is called alpine big wall climbing, which can be seen in Bugaboo, Alaska, Greenland, Baffin Island, Patagonia and even Antarctica. Climbing alpine big walls, climbers need to have skill of every thing, free rock, ice, mixed, aid climbing, back country skiing and glacier travel, some time even sea ice travel in fjord (in Baffin island and Greenland). Some climbers can even lead 5.10 free climb with plastic over boots. Needless to say it is done in extreme cold condition. Interestingly, in this situation, no body cares what style anymore; aid or free, red point or on-sight, alpine or siege style, who care. Climbers care only “to live or to die”. If fix line can be done, do it, who care. When Greg Child was climbing the Gasherbrum (IV?) the last half pitch is a smooth granite wall to the summit, no crack, no feature at all. He had to hummer a bolt ladder in order to reach the summit ( it was near 8000m). Noted that those old climbers they also hate bolts.
