This crag looked particularly fragile, though it's probably surprisingly stable.

Pen-y-ghent is on the main Pennine watershed of mainland Britain. Rainwater falling on the western side of the hill drains into the River Ribble and on to the Irish Sea, whereas rain from the same cloud, falling on this, the eastern side, drains into Pen-y-ghent Gill, joins the River Wharfe via Littondale, and flows to the North Sea.
