The gully between B and C Buttresses is well-defined only between the Middle Ledge and the Rake, where several short ice steps provide interest. Where it tops out at the Rake, there are three possible finishes:
1. Left-hand finish, consistent with grade;
2. Central icefall direct finish, III;
3. Right-hand finish, consistent with grade.
From the Rake, many continuations are possible on the Upper Tier.
