Big wall climbing is a form of rock climbing that takes place on long multi-pitch routes that normally require a full day, if not several days, to ascend. In addition, big wall routes are typically sustained and exposed, where the climbers remain suspended from the rock face, even sleeping hanging from the face, with limited options to sit down or escape unless they abseil back down the whole route. It is therefore a physically and mentally demanding form of climbing.

Leonardo Emilio Comici was an Italian mountain climber and caver. He made numerous ascents in the Eastern Alps, particularly in the Dolomites and in the Julian Alps. Comici was nicknamed the "Angel of the Dolomites".
