Freestyle skiing has two disciplines, aerials and moguls, and it became a medal sport in 1992.

There were too many rules and regulations for the young guys coming in, so they turned to the snowboard and to more freestyle skiing.

In the late 1990s a new style of freestyle skiing began to grow in popularity.

It has sections for alping skiing, freestyle skiing, skiing and biathlon, snowboarding, telemark skiing, football, handball and cycling.

For winter sports such as freestyle skiing and snowboarding, a half-pipe can be dug out of the ground or snow perhaps combined with snow buildup.
