Below the ledge of Pocket Protector find double cracks leading to an overhang. Climb this and pull the lip onto less steep terrain. There are two ways to finish: move up then angle right across slabby rock to ring anchors, or trend left into a gully/crack-system and follow this to a ledge belay station next to a bush. A 70m rope will get you back to the base of the route.
(Please note that the rock quality rapidly deteriorates higher above this ledge. The final few feet of the tower is not actually attached. It is not recommended to attempt to gain the true summit.)
A second pitch above the ring anchors was led by BS going to the bulge, then left, then up through bulges to the belay ledge.
Location
Left side of Trundle East face, below the Pocket Protector belay. Find the cracks with bright green lichen.
Bit of history: this was the first route we climbed out here. It was awesome, and a day to remember. It was a little disappointing to see so much lose rock at the top of the pinnacle, I know we both wanted to stand on top. We found a "great" 1/4 bolt up there (probably from the Baker era), and made an anchor to get down. The next time up, we went with a drill to install an anchor and start putting in routes, which ended up with us getting rained out and bumming. I remember feeling like we were getting nowhere fast, and cursing the weather.
