A hundred metres or so south of Llyn y Garnedd, in the foothills of Moelwyn Bach, is a strange circle. Not a crop but water. Could the ferocious heat of intergalactic engines have burnt deep into the peat as an alien spaceship parked up to enjoy the Vale of Ffestiniog? Does anyone have an alternative theory? There are another 3 similar, but less round, moats surrounding islands of peat.
Could they have been dug out for game-keeping purposes? Would the water have provided some protection for ground nesting birds?
