The sport of skeleton can be traced to 1882, when English soldiers constructed a toboggan track between the towns of Davos and Klosters in Switzerland. While toboggan tracks were not uncommon at the time, the added challenge of curves and bends in the Swiss track distinguished it from those of Canada and the United States. The source of the word is debated; some speculating the skeleton-like appearance original sleds, and others an incorrectly anglicized version of the Norwegian word for toboggan, "Kjelke".
