A maximum value experience not to be missed. You will find a bit of everything on this classic which has been described by at least one experienced regular as a "great 5.9 with a 5.11 crux". Your experience may vary but you will definitely consider an ascent worth your time.
Not recommended for a 5.9 leader.
Climb the thin crack (cruxy), traverse right then stem up the left-facing corner(strenuous) and finally face climb past the bulge to the top.
From the intersection of the East Face trail and Upper Broadway (base of Castor) turn right (North) and walk to the high point ~20 ft in front of you shaded by a pine tree. You will see a thin crack in the wall leading to a horizontal feature about 20' up.
A little bit of everything. Did you remember your small gear?
