Travelling south through the eastern Peak the gritstone gradually fizzles out, the long snaking crag escarpments giving way to more isolated outcrops. And just as it seems all the rock has turned decidedly pale and chossy, one last big finale remains, one last huge island of dark gritstone in a sea of limestone. Black Rocks; its name enough to scare off many, but it remains something of a hub of the climbing scene in this part of the Peak.
