Gunsmoke

Gunsmoke ascends a third and final chimney, different than the other two, and it is worth doing.

Climb up the back corner of the Firing Chamber, where 3 different sections of chimney intersect. A flaring, offset crack in the narrowest section of chimney offers a few reasonable points of protection sufficient to make the route safe as a trad lead. Climb this to the top, and belay on a large cordalette on some boulders.

Back in the Firing Chamber, the slot takes a right-hand turn and the wide initial chimney narrows significantly. This creates a corner with the intersection of 3 different widths of chimney, which is the route at hand.

1 set of Aliens from small to 1.5" will do just fine.
