I went for a walk to the summit of Pen y Fan this morning (it was in thick cloud despite the weather forecast, but that’s another story). I could some sunrise colour just after I started up the hill, which I duly photographed:
I had seen the summits were in cloud already, but decided to walk up there anyway for the exercise. On the summit, I had a coffee and some food before photographing the rocks. If you’ve ever been to the summit of Pen y Fan, you might have noticed rocks with patterns in them. The reason for this is sand – Pen y Fan is formed from Old Red Sandstone. These ripples in the sandstone were formed by the motion of the water over the sand, which means that millions of years ago the summit of Pen y Fan was once at the bottom of the sea!
