Mounds of processed slate aggregate
Brilliant photos, Graham. I am fascinated by the mounds of processed slate aggregate and the way they resemble the mountains behind. Very intriguing site.

Although I vaguely knew this place existed, I’d never seen photos of it. I’m also intrigued by the piles of processed slate, reminds me of the piles of coal at power stations.
