Telemark skiing is a ski technique that combines elements of Alpine and Nordic skiing. Telemark skiing is named after the Telemark region of Norway, where the discipline originated. Sondre Norheim is often credited for first demonstrating the turn in ski races, which included cross country, slalom and jumping, in Norway around 1868. Sondre Norheim also experimented with ski and binding design, introducing side cut to skis and heel bindings (like a cable). Telemark skiing was reborn in the 1971 in the United States. Doug Buzzell, Craig Hall, Greg Dalbey, Jack Marcial, and Rick Borcovec are credited reintroducing the style after reading the book Come Ski With Me by Stein Eriksen. Telemark skiing gained popularity during the 1970s and '80s. Telemark equipment crosses Alpine and Nordic ski gear. Generally, Telemark skiers use Alpine skis with specially designed Nordic style bindings that fix only the toe of the ski boot to the ski, thereby creating the "free heel." Telemark turns use a distinct lunging motion.
