Blues skies over Broxburn shale bing on Thursday morning.
A bing is another word for slag or spoil heap. This particular bing is shale waste and is part of the original oil boom which took place over 150 years ago in West Lothian. It always makes me think of Uluru/Ayers Rock when I see it. It is part of my own heritage too, since my ancestors worked down these mines.
