Lovely hill, extremely windy when I went up in December. I ascended up a path from the quarry side and beside a gate saw a bunch of stones which seemed to me could well be a former stone circle, although I cannot find anything on the old maps to confirm that. The stones are piled up at 57.664767, -2.715907.
As an aside I was using peakfinder.com to identify the hills I could see, what a great tool!
