Norheim closely resemble the shape of modern slalom skis. Norheim was the champion of the first downhill skiing competition, reportedly held in Oslo, Norway in 1868. Norheim impressed spectators when he used the stem christie in Christiania (Oslo) in 1868, the technique was originally called christiania turn (norwegian: christianiasving or kristianiasving) after the city (first printed in 1901 in guidelines for ski jumping). The telemark turn was the alternative technique. The christiania turn later developed into parallel turn as the standard technique in alpine skiing. The term "slalom" is from Norwegian dialects slalåm meaning a trail (låm) on a slope (sla). In Telemark in the 1800s, the steeper and more difficult trails were called ville låmir (wild trails). Skiing competitions in Telemark often began on a steep mountain, continued along a logging-slides (tømmerslepe) and was completed with a sharp turn (Telemark turn) on a field or frozen lake. This type of competition used the natural and typical terrain in Telemark. Some races were on "bumpy courses" (kneikelåm) and sometimes included "steep jumps" (sprøytehopp) for difficulty. The first known slalom competitions were presumably held in Telemark around 1870 in conjunction with ski jumping competitions, involving the same athletes and on slopes next to the ski jump. Husebyrennet from 1886 included svingrenn (turning competition on hills), the term slalåm had not been introduced at that time. Slalom was first used at a skiing competition in Sonnenberg in 1906. Two to three decades later, the sport spread to the rest of Europe and the US. The first slalom ski competition occurred in Mürren, Switzerland in 1922. Technique A skier following the fall line will reach the maximum possible speed for that slope. A skier with skis pointed perpendicular to the fall line, across the hill instead of down it, will accelerate more slowly. The speed of descent down any given hill can be controlled by changing the angle of motion in relation to the fall line, skiing across the hill rather than down it. Downhill skiing technique focuses on the use of turns to smoothly turn the skis from one direction to another. Additionally, the skier can use the same techniques to turn the ski away from the direction of movement, generating skidding forces between the skis and snow which further slow the descent. Good technique results in a fluid flowing motion from one descent angle to another one, adjusting the angle as
