Otto Bahn is the very flat and boring traverse from the top of the Rendezvous lift or the Blackjack lift and takes you over to the bottom of the Mountain Chief lift.
Even though it is very boring on this trail, it serves a couple of very important purposes.
One, it is a great way for the intermediate to see the entire Copper Bowl without having to go down anything difficult and then make a decision where he or she belongs.
Copper Bowl has many different aspects and pitches and can be great for the intermediate all the way to the expert.
Second, it is the direct route to get to the free snow cat; just follow the traverse straight across nearing the end until you see the cat in the distance.
