Hey Steve, don't you live in Mammoth area?

next time, just skip Reds area.

much prettier options southbound:

(A) go out Duck Pass to join JMT

(B) go up from Lake George to Mammoth Crest, turn left at the red scree area on the trail leading to Deer Lakes. Go cross country up the talus slope above the lakes ,across a divide, then down to the Duck Lake trail as it descends on the south side of Duck Pass ( note: this route is easier to figure out going the other direction, sorry.)
