This is a depiction of skaði, the Norse Goddess associated with skiing, bowhunting, winter and mountains. She is also reffered to as Öndurguð, which means "Ski God" and Öndurdis, which means "Ski Lady"
Anyhow, early primitive carvings from around 5000 B.C. depict a skier with one pole, located in the Nordland region of Norway. The first primitive ski was found in a peat bog in Hoting, Sweden which dates back to 2500 or 4500 B.C.
