Today's freestyle skiing is but a distant relative to that of the 1970's mogul-bashing ''hot doggers.'' The focus is on the terrain park, a designated section of a ski trail that is sculptured and groomed with features like flat-crowned tabletop jumps, metal rails and plastic-coated rectangular boxes for sliding on and halfpipes scooped out of the snow. In their ultimate incarnation, like the slope-style course of the annual ESPN Winter X Games, terrain parks enable skiers to soar off jumps while throwing 720-degree revolutions and to slide along steeply sloped rails three feet off the ground.
