No theres two chairs above the gondola, but there kind of beside each other one operating one side of the mountain and the other operating the other side of the mountain. One of them also goes a bit lower down. But to get higher than that will only be on weekends, as long as snow permits, and i doubt that youll beable to ski any lower than those two chairs.
