While the headline "grotty peak lime quarry has loose rock" won't surprise many, we pulled some rock off climbing in Blackwell Halt yesterday and required a trip to A+E (thankfully not serious). The blocks looked solid before they unexpectedly parted company sending football sized chunks down to my belayer from 3/4 height.
My climbing partner had already described the place as a "disgrace to climbing" (obviously not an aficionado of peak limestone).
I doubt there has been serious change to the grades but suspect there's bit more to come, treat with caution.
