It's called Carleton Mill, it's several miles north, and there's just one stone left, in a hedge, called King Stone, or something. The Megalithic Portal has it listed - no photographs - I haven't been over that side of the fell for many years. It's where my in-laws are from. My father-in-law was a Carlisle sculptor, who was raised at Greystoke; his dad was a chocolate box Lakeland watercolourist.
