I've been told the rating is sandbagged, that this is much harder than 5.9. Seemed on the easy side of that grade the day we sent it - which involved creating a makeshift "rack", since neither of us brought one. A couple bolt hangers, some resident stones, and a knotted cord or two sufficed.
Directions are simple: climb the crack. The top-out is the mental, and perhaps physical, crux.
On the Jammer Ledge, right end, just past the low roof; at a vertical crack which tapers from hands down low, to fingers higher up.
