Lyn Cau is a stunning glacial lake at an elevation of 480m on the flanks of Cadair Idris in southern Snowdonia. Surrounded by 400m high mountain walls, the rising sun shines into the corrie only in late spring and late summer. Reflections at this elevation can be rare. I ascended in darkness under cloudy skies but the weather forecast indicated that the cloud would break up just after sunrise. Sure enough it did and the first sun of the day shone into the back of the corrie, giving two pools of light in a pleasing position. Fortunately I had taken a fisheye lens with me, which at 15mm focal length enabled me to get the whole lake in frame.
