Wikipedia reports that Telemark skiing (also known as free heel skiing) is a form of skiing using the Telemark turn. The skis used for telemarking have a binding that only connects the boot to the ski at the toes, just as in cross-country skiing.
The technique is named after the Telemark region of Norway, just as the stem Christie turn was named after Christiania (now Oslo), Norway.
As well as inventing the Telemark turn, Sondre Norheim and his fellow skiers used and refined parallel skiing techniques. Thus, while the Telemark is part of early skiing’s foundation, parallel techniques are of equal importance.
