Noticed in logbooks today that someone doing Lead Vein thrombosis at deep rake had commented that it was way easier than before and thought it had been chipped. I live local so went and had a look, the rock here is soft so the backs of things can get eroded out and get deeper and things chage from first ascents etc.however a 4 finger right angled edge has been created on top of a chert band on the hardest move of the route to the left of the 2nd to last bolt. You could possibly blame erosion but it's got perfectly right angled sides to it and on its width.
Most ascentionists used to go to the right of this bolt via sketchy crimps then reached left to a positive crimp. One of the holds to the right of this bolt also looks messed with. Yes it's only a scruffy quarry but people need to behave! Pic on my profile of the chip
