Looks a bit popular and crowded ... :-)
Suggestion on the MP description:
Current : From the end of P4, continue up ~500 vertical feet of snow, ice, and easy mixed to the summit. This portion of the route is shared with Right Gully, Ravine, and The Pencil.
Suggested: From the end of P4 continue up remaining ~500 vertical feet of the Right Gully Route to the summit.
That is list the primary route, the fact that other "variations" join in are moot.
