RHYang: Thanks for the info, and the helpful picture! That seems to be consistent with my research, which shows two likely spots to traverse the ridge as shown in the pictures below. I think your picture shows the "back" (north) side of the upper gap that I identified.
I'm already committed to the Helen Lake portion of the trip (we have several newbies on our team) but no regrets there, especially in early season. A West Face Gully add-on would be great once I'm acclimatized, although it's off the beaten track and the traverse might be challenging. But that's why we're there in the first place, right?
