Fairly easy climbing through a low slot located behind a tree for about 30'. Take the one to the left (5.7+) as the route gets kind of fisty. The route terminates in an off-width (Paul Piana refers to this as a "chimney like structure" - but its not unless you are 4' tall and 60 lbs). Fire in your big cam and lay back off of the flake on the face.
Gear to at least a #4 Camalot - might be more comfortable with a Big Bro.
This is on the far right of the Hahn Wall near the southwest end of Blair I. The descent is a walk off to the south.
