Peake-o-matic

Castleton, in the High Peaks of Derbyshire, is a small town sitting against a hill. Cutting into the hill, like a slice taken out of a dutch cheese, is a gorge which leads to a huge cavern. Out of the cavern flows a stream which is populated by brown trout. At the top of the gorge, right on the edge, (top left of the middle photo) sits the keep of Peveril Castle, though it isn't visible because of the trees.
