Leadville, Colorado, celebrates winter during the annual Crystal Carnival March 1-3, 2013, highlighted by the town’s time-honored tradition of ski joring, a unique winter sport combining horses and skiing.

Since 1949, Leadville’s streets have been converted to winter racetracks for the annual ski joring competition. Horses and their riders pull skiers along the snow-packed roadways and over jumps while the skier spears rings in a timed competition.

The sport originated in Scandinavia hundreds of years ago, with reindeer in place of horses. It migrated to the U.S. and became popular with ranchers, who used horses and rope to pull skiers along a straightaway.

Today, the highly competitive sport takes place in several states across the U.S., as well as in several other countries that use variations of pulling power, such as dogs, mules or snowmobiles.

Ski joring consists of a horse and rider pulling a skier over jumps and along a straightaway to spear rings.

This year’s Leadville competition will feature four classes of ski teams: Open Class for experienced teams, Sport Class for beginners, Legends Class for seasoned teams, and the Snowmobile Class.

The competition takes place alongside the Crystal Carnival, another Leadville tradition, established in 1895. During that year’s winter, local businessmen built the Ice Palace to counter the slowing mining economy. The builders cut 5,000 tons of ice from nearby lakes to sculpt life-size townspeople, a skating rink and the Gallery of Commerce that served frozen produce, beer and other items.

The first Crystal Carnival attracted crowds that came by train from Denver and around the country and featured a parade and fireworks. This year’s carnival has expanded its original bounds, and, coupled with the ski joring competition, promises to be fun for the whole family.
