FYI, you can't get from the top of the Timberjack to the next tier very easily. It would involve a 5th class dirt romp and would be pretty scary. Gorilla My Dreams is a much better option for this linkup.
DRep and I hiked up there once to check it out. It didn't seem worth the while once we actually got up to it. Plus, that whole southwest face had major rockfall a couple times in the the last year. The gully below the buttress was littered with debris and I didn't feel safe being below it.
It looks like they traversed from the saddle out to the bowl on the north side, then ran out of time after climbing for a bit and traversed back to the west ridge and back down to the saddle.
P.S. It's in the Madison Range, not the Missions.
It's 5.8 according to Cummins.
