If you are skiing the steeps & attaining the angles required for dynamic turns, your inside knee, hip & hand will all get close to the snow. In some circumstances that hand will graze the snow. However, it can also be an indicator that you are a). letting your hips & shoulders square up with your skis, b). using upper body rotation to hurry the turn completion, c). leaning into the hill.
Ideally the inside shoulder, arm, hip, knee & foot all stay slightly higher & ahead of the outside...
...but as soon as one or more of those indicators gets lazy
, this is the outcome
(inside ski slips slightly forward, hips square up, shoulder drops back, bend at waist & inside hand hits the snow).
We were skiing the Avi chutes off Lincoln Mountain at Mammoth over Memorial weekend & the local we skied with claimed that they were 47 degrees. If that is the case even for a short section, I could see how many of the pitches off the top of the Gondola or chair 23 could approach 40 degrees.
