See The Fly Couloir
for more details. The Zipper is a little bit narrower and a different aspect (more West facing) so beware.
Same deal as The Fly Couloir
but with a little less elevation gain, a little steeper, and a little narrower. Overall it is a bit more of a technical line, but just as fun and has a great run-out zone. Be sure to observe conditions from the road on the way in (it's super easy to spot) to make sure the choke near the top is filled in. In early season / light snow years this line can look filled in but be deceptively shallow in the couloir.
