The open book left of the upper section of Blow Hole is a rather obvious line but lacks an obvious start. Getting there is the hard part. Begin about 10' left of Blow Hole in seams.. a long reach from a lieback (crux) will get you to some edges that let you move left to join the start of the featured upper dihedral. You can place a #3 or #4 cam before committing to the crux moves. The open book is fun sustained 5.10-ish stemming to the top.
Location
Climb starts 10' left of Blow Hole, and ends in the open book left of Blow Hole.
Protection
1 set nuts, 1 set cams up to a 3" cam. Build an anchor off your gear at the top of the climb. Like many at the Playground, this one ends at the ledge 15' below the top, so tieing off dying trees is not a good choice.
