Aerial skiers launch themselves 50 feet or more into the air off a jump made of snow and land on a steep slope where snow is chopped for a softened landing.  In the air athletes perform multiple combinations of intricate flips and twists.  The jump that has the highest degree of difficulty performed is the "hurricane" thrown by Jeret "Speedy" Peterson- three flips and five twists, the second flip has three twists!  Many athletes that compete in aerials were former gymnasts.  Aerials were added to the Olympics in 1994.

Halfpipe skiers launch themselves out of the halfpipe performing a series of jumps, tricks and spins.  Athletes are judged for their degree of difficulty, amplitude, and execution of each trick performed.  Currently halfpipe events are at the USSA, NorAm, and World Cup levels.  Halfpipe is currently not in the Olympics.

Moguls skiers charge through a field of snowy bumps with two mandatory jumps that separate the course into three sections.  Skiers are judged for their technique, how well they perform their two obligatory jumps, and speed.  Moguls was added to the Olympics in 1992.  In the Olympics athletes compete in single moguls however USSA, NorAm, and World Cup tours all have dual moguls events.  Dual moguls are where athletes face off head to head, side by side, and the best skier advances. 

Ski Cross is the newest Olympic discipline. The event course is a mix between traditional alpine racing and motocross with a variety of terrain features including rollers, banks, table tops, step downs, and pro jumps.  Athletes compete in heats of four to six, and the first person through the finish is declared the winner.  The events are very exciting to watch due to the challenging courses, side by side competition, and the tight passing opportunities.
