The link provides some additional detail information on this sad event that I had not seen before. Inspecting the photos in the linked report and comparing them with my own, it appears that the hiker may have not been descending the optimal route from Jigsaw Pass, which is the right hand gully (as seen from the Bishop Pass direction). She was descending a gully more to the left, which I guess led into some class 4 terrain, where the accident happened.
Even the best route is tricky and a bit dangerous. Hikers beware!
