Llyn Y Caseg Fraith is perched on the edge of a ridge with fantastic views to Glyder Fach and across to Tryfan. The pools in the area are fascinating; the inner walls drop vertically by two feet or so to a dark lifeless base. In the right light they appear almost black.
As the morning began it was clear that there was no prospect of a sunrise, but occasional gaps in the cloud gave hope. Long after sunrise there was a burst of light that lasted perhaps a minute and coincided with a slight lift in the cloud level. Tryfan and Glyder Fach were still in shadow and appear almost black in comparison to the sunlit grass on the edge of the pool. Lighting doesn't get better than this!
I will be returning to Llyn y Caseg Fraith sometime soon to see what else the location can provide.
