Hi Jim, I enjoyed your trip report very much. It is well written with detailed description of the area. Richard P. and I went down Miter basin from Mt. Irvine and Mt. Mallory side and camped out by a small lake north side of Sky-Blue lake and went out through Crabtree pass.
I'll read your trip report many times over before my future trip there.
I haven't decided how I want to get Chamberling and Newcomb. Either climb into Perrin Creek from Rock Creek or go over Crabtree Pass. A long way whichever way I go.
