The story behind this video

Llyn Alwen reservoir in North Wales is an oasis of calm and quiet compared to its larger and much more heavily visited neighbour, Llyn Brenig.

My wife Liz and I come here often, for a walk around the forested margins of the lake, nibbling on bilberries as we go along, enjoying the complete absense of traffic noise and other man-made intrusions to the natural order of things.

However, on this occasion in August 2018, with a cold wind blowing heavy clouds over the landscape we ventured no further than the impressive stone dam at the end of the reservoir, where I set my camera up to record this two part time lapse of those dramatic clouds.

Much more interesting from a photographic point of view than clear blue skies, but not too good if you want a pleasant hike around the lake.
