Hop turns are a great skill to use on off-piste slopes that are too narrow for big arcing turns, such as couloirs, chutes and gullies.

Hop Turn Technique
To execute a hop turn, you want to focus on being really low and exploding upwards and pivoting around your ski pole.
First, set your ski edges as you plant your pole and then explode and extend all at once to get your skis off the snow. Then pivot your skis around your ski pole and as you land you'll plant your other pole and flex your knees to suck up all of that force to be able to use in your next hop turn.
