Völklingen Ironworks, view from the charging platform

(ISO 100, f8 @ 30mm, 1/125sec., 14:21)

I am standing on the charging platform here approx. 27m above the ground and we are looking towards one of the three slag heaps of the ironworks. The slag mountains are locally called “Hostenbacher Alps” and reach a height of 90 to 130m. Interestingly the heat inside these slag heaps might have contributed to the development of a great variety of lichens. Scientific research has found 90 different species spreading on the slags today.
