This problem starts on the left side of the face under the prominant roof and prow. Climbs up with easy pulls on jugs to the lip of the roof where one must make comminting crux moves up the prow. I'm not sure it's quite V3, the actual moves seemed just a little easier. The damn thing is so high up though, that the highball factor might add a little to the grade. This problem is a classic. The rock is great, the holds are great, the moves are great, the postion is great, even the exposure is great (hard to find in a boulder problem). Definitely don't want to fall from the crux....
Protection
This problem is well over 20 ft. high. A pad is some reassurance. It is topropable as well.
If you can keep your wits about you through a reachy crux, it's smooth sailing over great holds.... A big pad and a good spotter can help to ease the jitters.... Definitely gets the grade because of the height and not the difficulty.
This used to be a fun lead, 5.10-. The first pro was a nut, then a fixed pin close to the crux, and a bolt on top. Both the pin and bolt are gone now. The bolt was useful for holding a sling over the summit horn in place. Without the bolt, Jaws is not really a good TR anymore.
