Yeccaph Mesa: Reach White Orb on middle cliff
Behind the cliff is a Power Button (partial circle). Once it's activated, the two air lifts behind the cliff are ready to be used. Jump onto the first air lift and make your way on the second. As you reach full height on the second air lift, hold the Float button (RT on Xbox) and immediately drift left. You'll be able to land on top of the cliffside where the White Orb is located.
