This route climbs the obvious steep flared chimney with the handcrack in the back. Start by scrambling up to the base of the crack below the chimney, then lieback it to a rest at the base of the chimney. Now jamb the perfect splitter handcrack for 40 feet, then scramble up to the tree for your anchor.
This route doesn't see a lot of traffic, but is very good.
Location
Hike the Inner Wall trail up towards Toxic Shock. Just after the cave look for a faint trail heading up the gully to the right towards the right end of the Trapped Balls cliff. Scramble along the edge until you encounter the first ledge with the moss scraped off. Traverse accross to the left here then up to reach the base.
Protection
