Need to Know

This couloir is pretty steep, needs lots of snow to be filled in, and it's not very wide. Don't fall or you'll likely be seriously injured.


A long approach to some one of the most amazing couloir skis I've had the pleasure of doing. This is well worth the effort to get there. It's a very steep couloir (and it's sustained). It's not very wide which makes it somewhat challenging. If you're looking for a fun challenge, this could be the route for you.
