Did this on Sunday after climbing Torture Garden. It is a great pitch...reminded me of High E, but with steep juggy laybacking rather than steep juggy face. The gear is bomber and the climbing is continuous and exciting until the dirty top-out. Torture Garden has good climbing, but is scary and a bit dirty. Yellow Crack's last pitch could also be reached easily by climbing P1 and P2 of Blistered Toe (5.7 PG). I highly recommend this if you're not up for the 5.8 PG-R climbing on Torture Garden. It is worth getting up there for Yellow Crack.
There's a rap anchor at the top of Yellow Crack which gets you to another anchor on a tree just below a huge ledge (with one 60m rope). From here, 2 ropes are needed to reach the ground, or a pendulum rappel to climbers left to reach another tree and then to the ground (with one 60m rope). Any link-up here is worth doing, either Blistered Toe/Yellow Crack or Blistered Toe/Torture Garden/Yellow Crack or Torture Garden/Yellow Crack (we did this one...the thin crack after the traverse on P1 is great).
