Begin on the obvious big flake and move up through the holds, when you reach the just in the middle of the roof stay to the right all the way to the end.


This can be found up past the swan, the spiders drum, and the turd. The boulder sits a good bit below 'The Magic Touch' boulder.

I added a low start adding 7 moves, start left hand underneath the roof on a sloping crimp, right hand on the opposing side on a small flat crimp, toe hook out right, bump right hand to a better crimp, one arm campus to a left hand crimp, match next to the left with the right, make a long pull to a right hand crimp, match with the left, make a long move to the right to join the first hold of X Chromosone, continue and finish all the way right on X Chromosone. The sit is called SPIRAL HELIX and the grade is around V10.
