the track was made by bolting seven layers of wood. in most places on the ride, there were two layers of southern yellow pine, which sat atop five layers of douglas-fir. older sections of track still had seven layers of douglas-fir (mostly on the lift) and there were refurbished sections of track with seven layers of southern pine. a strip of steel was bolted onto the top layer of wood track and three-inch-wide pieces of steel were bolted onto the sides.
