In an attempt to walk off the effects of too many sticky toffee puddings, I climbed a small lump of a hill called Castle Crag in Borrowdale. I wasn't expecting this sight at the top. An old abandoned slate quarry where people have been placing slates of various sizes in an upright position. With the mist wafting by, the effect was a combination of an eerie graveyard and an alien planet from Star Trek.
