The chamber of secrets is located just south of the Sourcerer's stone (aka BLM highpoint, aka pole cat rock). Most routes are on the west face where some excellent trad can be found.
Getting There
If approaching from castle creek, continue 150 yards past the jug wall through a 10-20' wide gulley. If approaching from Castle rock, take the Johnson Creek trail and head up toward the tower just S of the BLM highpoint. 30 min. from parking lot.
