Blue stone

The stone is described as whinstone so presumably is dolerite which originated from the Whin Sill outcrops. The Sill can be seen in outcrops all over the north and can be seen from Eastern Cumbria to the Northumbrian coast. It is this rock from which the beautiful, group XVIII, axe hammers are made.

I think it is the same stuff that's so prevalent up on the cuestas around Haltwhistle. It's kinda bluey, and whilst I did once hold a candle for the idea that one of the mad, bad and dangerous to know Deleval family may have nicked a bit of Stonehenge, it's not the same kind of stone.
