Chamonix, France is home to Vallee Blanche which has a vertical drop of 2807 meters or 9209 vertical feet. However, there is a company that is designing an indoor corkscrew like ski-run known as Ski-Trac that could chump all ski runs in vert. If ever built,- Ski-Trac could provide an infinitely long ski run that could last the rest of your life.

At the top speed of 30 km/h (19 mph), the slope-stretching magic of the rotating deck becomes apparent. As the skier zigzags downhill he is constantly being taken back up again by the on-coming snow and may in fact never reach the bottom!


In one hour he has traveled 30 kilometres (19 miles) over the snow, making the Ski-Trac the longest ski run in the world.

The ability to provide a ski run vastly in excess of the size of its structure will see the Ski-Trac become the standard method of indoor skiing throughout the world.

Origin of the Ski-Trac: The Ski-Trac was invented, designed and developed by Kevin Ferris of Brisbane, Australia. The first snow tests of the unique snow-making eco-system took place in Townsville November 1997 in association with George Jennings of Woomera Snow Guns, Canberra. A one-tenth size test model was built in a factory at Taren Point in Sydney. Systems development took place with the assistance of Richard Worsdall of Ski-Trac’s project management company Kinlay Neill Worsdall, with engineering development by Meinhardt, Sydney.

Using new Mag-lev technology, the snow deck, with its 200 mm (8 in) snow cover will “float” on an electro-magnetic field without the need for wheels, thus ensuring frictionless, vibrationless, silent, and maintenance-free rotation. Drive power will be supplied by linear motor.
