This is an unusual locality, a functioning power station. The minerals found here were collected from the material (limestone) removed during the excavation of the cooling water intake tunnel and open channel in the 1970s.
The minerals occurred in cavities in the limestone. The best specimens collected in 1974 were very sharp, colorless crystals of celestine to 5 cm and opaque blue crystals to ~8 cm.
