Four Welsh Slags

I was messaged yesterday by a Liam Olds of The Colliery Spoil Biodiversity Initiative asking to use this photograph for talks that he does....the next being on 20th in Cardiff. He's not a member of Blipfoto but found it - showing that our photo's do get out to the wider world!

Seeing as it was about two and a half years ago, I returned this afternoon and did another. There's quite a few of these slag or spoil heaps in South Wales but this is my favourite as I love the shape of the three smaller ones that look like pyramids!
