The following year, Corcoran and Doug Pfeiffer, organized the first National Open Championships of Freestyle Skiing on the Sunnyside trails.

Some of these competitors, such as Wayne Wong, Floyd Wilkie, and George Askevold, stayed at Waterville Valley as coaches of the first Freestyle Ski Team.

Aerialists train for their jumping maneuvers during the summer months by skiing on specially constructed water ramps and landing in a large swimming pool.

The skier then skis off the wooden jump and lands safely in a large swimming pool.

Moguls are a series of bumps on a trail formed when skiers push the snow into mounds or piles as they execute short-radius turns.

In competitions, athletes are judged on their technique as well as on their speed by mastering the bumps in a calm yet aggressive way.

For a short period of time (in the 1980s) there was also pair ballet competitions, a variation of ballet, where two people performed tricks that not only included spins, jumps and leg crossing but also lifts and sychronic movements and was similar to ice dancing.

The routines were scored by judges who assessed the choreography, technical difficulty, and mastery of skills demonstrated by the competitors.

Early innovators in the sport were American Jan Bucher, Park Smalley, Swiss Conny Kissling and German Hermann Reitberger.

The first skier who performed a one handed pole flip in a world cup competition was German Richard Schabl in the early 1980s.

The International Ski Federation ceased all formal competition of this event after 2000 because they focused on both aerials (1990) and moguls (1992) for making it an Olympic discipline.

Slopestyle became an Olympic event, in both skiing and snowboarding forms, at the 2014 Winter Games in Sochi, Russia.
