This route ascends an offwidth/chimney to a nice thin dihedral. While the climbing is brief, its really pleasant, easy to protect and is a fine way to reach the summit of Hidden Rock with outstanding views.
This route climbs the obvious thin dihedral on the far left side of Hidden Dome - Northeast Face, about 100 feet left of Too Secret to Find. To descend from the top of Hidden Dome, easy scrambling east leads to a scary chasm jump to the ground. Alternatively work around unpleasantly to the rap anchor above Screaming Poodle.
Gear thin nuts and cams 3", most people will want a 4" cam, gear anchor.
