Skiing above Sorfjorden in Lyngen Alps, Norway. Norwegians are the worlds first skiers. In the 1940s there was one place to ski. In Idaho "Sun Valley". I believe it was built for a Sonja Henie Movie in the 1930s, early 40s. Few people tried the slopes. It caught on through movies etc. Sonja Henie - famous Norsk movie star. Winter sports, Skating primarily.
