Thanks for all of the beta! I just tapped into the Trip Reports archive and I have to say that is a fantastic feature of this site and thanks to all of those who have shared their experiences there! I still haven't settled on a strategy, but I am getting a better idea of what to expect.
The Mountaineers Creek approach/Sherpa Glacier descent sounds like the more direct path, but introduces alot of variables that make me wonder if the Ingalls Pass approach / Cascade Couloir descent might be a safer bet for someone who is "onsighting".
A couple more questions - is "The Notch" bivy the saddle in the ridge just below the Great Gendarme?
Also, what is the best map for this area? Trails Illustrated?
