A little quotation:
"It is probably no exaggeration to say that for the recreational skier, the pure carved turn would have been impossible a few years ago without the tremendous improvements that have since been made in ski equipment. Skis are important. Here the carved turn is aided by the increasing sophistication of the sidecut and torsional properties being built into the newer skis today. Edges must also be superior. And for carving turns, boots should be stiff at the sides to increase edging power from the knee action, while giving forward action at the ankle.
"A pure carved turn makes maximum use of the design of the ski and a minimum of body motion. There is no lift or up motion, and the skis carve a lovely, narrow track ... the skier seems to come out of the turn with more speed than when he started. ... The carved turn is perhaps best made with a slightly counterrotated position, but there is no need to be doctrinaire about this. The turns can be equally well made with the upper body more or less square over the skis."
Fairly unexceptional stuff ... except that it's taken from the 1970 Edition of "Ski Magazine's Encyclopedia of Skiing" (with one minor terminology change: "side camber" to "sidecut").
Worth keeping in mind when some semi-imbecile on YouTube claims snowboarders invented carving.
