For the White Pass turn, lift your uphill ski at the beginning of the transition. Your outside ski will end-up up at your boot cuff for the first half of the turn. Once down in the fall line, drop the outside ski on the snow to complete the turn and prepare for the next transition.
This drill forces the racer to initiate the turn in the inside skis, a good skill to ensure a proper active inside ski in regular turns.
