Control can be learned on easy ridges and rocks. With no risk, a skier can assay his coordination and develop his ability by climbing at the base of a cliff, on progressively higher angles and tinier holds, where he is never so far above a landing strip that he cannot safely jump if something happens to his controls. Competition afforded by a follow-the-leader process will speed his early progress and that of his friends. Without increasing his exposure to difficulty he can learn the function of the rope, carabiner, piton, and footgear. Finally, and still without exposing himself to great height until he is ready, he can learn how his control and his climbing aids are combined to provide corrective measures and to build a team.
