Wen arriving at North Rock this is the first real obvious crack encountered on the way up it's length, perhaps 50' right of the lowest termination. The system is slightly left-leaning and wide. The 5.2 grade Erikson gave it is a bit light, but the climb is still quite easy at 5.4 or 5.5. The climb is also reasonably clean of dirt, though some friable rock still lies on it.
A set of cams to 4" will do just fine. Wide pieces would be nice to sew it up, but I don't think that it is necessary.
