This is the last route on the map. I found this from the bottom, walking upstream, past everything, around past the rock narrows. It ascends an ice ramp (with the left edge at a rock arete), then right and up short column to the top, which ended in a very small natural drainage (read: very thin/dirt mantle onto the top). Maybe a variation the way I did it? [I'm just taking a chance and filling in some omissions. It clearly wasn't WI3 the way I did it.] Towelie
appears to be to the right, based on the Official 2008 Map rating.
