Uller by W. Heine

In Norse mythology, Ull (or Ullr or Uller) is the son of Sif, and the stepson of Thor. He is thought to be the god of Winter, of hunting, of hand-to-hand combat, and of the willow tree. His name means "glory". He was said to be a great archer and skier who left blazing trails across the sky.

For this reason he is celebrated in modern times as the god of skiing. His name is used as a name for ski lodges like the House of Ullr at Thredbo, New South Wales. ULLR Labs make smartphone applications to help people avoid avalanches.
