Attention, instructors: In the bumps, it's no longer all about the turn.
If traditional instructors are ever going to develop decent mogul skiing and mogul instruction skills, they're going to have to make a major change in the way they think about skiing.
On groomed terrain, yes, the turn is nearly all important, nearly all that matters, nearly your only source of control. In the mogul field, however, the turn is only about half of what matters. I'd even argue that it's less than half of what matters. In the mogul field, absorption and extension -- the up-and-down leg movements that allow your skis to ride smoothly along the bumpy contours of the snow -- are just as important, and perhaps even more important, than the turn.
Because instructors pay a lot of attention to the ways in which alpine racers ski, and almost no attention to the ways in which mogul skiers ski, the mogul skier's absorption and extension movements, which don't exist to any appreciable degree on groomed terrain, are practically unknown to the instructing establishment. And this is why most instructors cannot ski the bumps well or teach you to ski the bumps well. Their skiing model, their conception of the sport, precludes the existence of the very skills, the very movements, that make mogul skiing possible.
