Skiing 2009 Calendar. Skiing evolved into a popular recreational and competitive activity during the mid to late 20th century. Before this, the earlier form of skiing was primarily used for transportation. This skiing calendar features the more extreme side of the sport. Away from Downhill or Alpine recreational skiing, this calendar is most certainly 'off-piste'. The calendar has a month to view grid with outrageous and extreme skiing photographs taken by Marc Muench.
