3213 BCE to 3070 BCE
The first hints to the existence of skis are on forty-five hundred to five thousand year old rock drawings, e.g., at Rødøy in Norway (discovered 1933) or at Steinkjer (discovered 2001), which depict a man on skis holding a stick.
The oldest known ski, Kalvträskskidan was found in 1924 in a mire near the village of Kalvträsk in the municipality of Skellefteå, Sweden, and has been carbon dated to roughly 3200 BCE.
The earliest people to ski in Fennoscandia were the distant ancestors of modern day Sami.
