e/Clean climbing

Information
has gloss	eng: Clean climbing is a rock climbing term that describes techniques and equipment which climbers use in order to avoid damage to the rock. These techniques date at least in part from the 1920s and earlier in England, but the term itself may have emerged in about 1970 during the widespread and rapid adoption in the United States and Canada of nuts (also called chocks), and the very similar but often larger "hexes," in preference to pitons, which damaged rock and were more difficult and time-consuming to install. Pitons were thus eliminated as a primary means of protection in a period of less than three years.

Ce style sest développé au Royaume-Uni et aux États-Unis dans les années 1970, avec dune part lapparition et la généralisation de lusage des coinceurs, et dautre part la prise de conscience des dégâts occasionnés par les pitonnages et dépitonnages dans les fissures (le style dominant dans les années 1950 et 1960 était lescalade artificielle, sur pitons et spits).
