sites. Snow grooming equipment Snow grooming equipment that is usually towed by vehicle like Side-by-Side, UTV, or Snow Mobile and is used for snow grooming narrow paths, laying Nordic and Cross-country ski trails, Fat bike trails. These small and practical snow groomers are excellent for making delicate corduroy trails that a large snow groomer cannot access. Snow farming Snow farming is the use of obstacles, equipment and knowledge about management of snow in order to strategically manipulate snow coverage. Often this is done for the purpose of skiing or even preventing snow drift in certain areas like roads. The most popular obstacle is the snow fence, which is used to create drifts and collect more snow in a given area than would otherwise naturally occur. The snow can be moved to other areas and groomed with the use of a snow groomer. Sometimes the snow fence is readily movable in order to maximize the collection of blown snow, despite wind direction changes. In Mora, Minnesota, the annual Vasaloppet USA cross-country ski race would be unable to happen without the use of snow farming due to lack of natural snow in recent years. Snow runway construction Snow grooming is used in construction and maintenance of airstrips to support research stations in Antarctica. U.S. Army Cold Regions Research and Engineering Laboratory (CRREL) researchers described the engineering parameters necessary to make improvements to natural snow for use in landing fields. One level of improvement is used to support aircraft with skis. In 2016, CRREL researchers perfected field preparation practices that allow for use of heavy military transport and other wheeled aircraft on snow runways in Antarctica. Proof-of-concept tests employed a C-17. Wheeled aircraft capability exists at the US McMurdo Station and ski landings are routine at the Australian Davis Station.
