when starting up the initial double cracks of indecent exposure branch off to the left and follow the weakness' up. This should lead you to a nice little belay ledge just left of the indecent gulley. belay here and either continue up and left reaching lunch ledge on the 2nd pitch or finish on the final pitch of indecent. either way its a nice variation that aviods the worst of the gulley thrash.
Location
branch left out of the indecent exposure double cracks and stay on the face.
Protection
wireds and cams. I never came across the fixed pro but this route seems wander so I might have gone a different way than the FA.
For my second ascent of the thumb on sept 29th 2009 I chose this fun variation to stay out of the gulley. By the time we got to the summit the winds were howling at about 50+ mph!!! The next day I wake up to snow capped peaks, what timing!
