In reply to Misha:
Not on Troutdale Pinnacle, but I once encountered something very similar behind a jug-hold halfway up the final pitch of Preposterous Tales. If you've climb it you'll understand my incredulity. Someone (just possibly some dog, but I very much doubt it) must have taken a dump in the hollow at the top, probably not realising that an inadvertent slip would send them straight down a 20m chute followed by a 30m freefall into the ocean.
