First pitch of the waterway traverses in from the left and ends on the big ledge to the left of the GA P3 anchor. Bring cam hooks, ballnuts, and a big hook to climb the pitch clean. You can walk along the ledge to get there.
CFF and I removed some 1/4 split shanks and replaced them with 1/2 SS 5 piece bolts. The plan was to rap down to replace the bolts of the first pitch of GA, but it was too hot, we were too lazy, we ran out of beer, etc...
The arch pitch doesn't need any hammering. Bring cam hooks, ballnuts, and brass.
The pitch after the arch involves some sketchy hooking on cornflakes stuck to the wall. Have fun with that.
