It's time to celebrate the simple joys of ice skating. Here in the Northern Hemisphere, winter has provided frozen playgrounds for all to enjoy. Ice skating takes many forms, from speed skating to professional hockey to figure skating to sliding around on a pond. In the Netherlands, hope was high that the Elfstedentocht, or Eleven Cities Tour, could take place on frozen canals for the first time since 1997, but ice thickness was thus far insufficient to support the estimated 16,000 skaters who would take part in the 124 mile event. Techendorf, Austria hosted an alternative event for 6,000. Gathered here are images of people enjoying the combination of smooth ice and steel blades. -- Lane Turner (33 photos total) A family skates across Mendenhall Lake in Juneau, Alaska on January 16, 2012.
