Anthropogenic forms are important components of the Upper Silesian landscape. Among them, the slag and spoil dumps of coal, ferrous and non-ferrous metals, have an extraordinary aesthetic and document value - they provide evidence of the history of industrialization of this region. Waste rock accumulated in the dumping areas might be a source of utilizable material; thus the existence of most of the dumps is transitional phenomenon. However, a part of forms built from the rocks of low technical parameters have pretty big chance to remain. It happens in Western Europe that some of the dumps are left in the landscape as the evidence of history. They are usually spectacular objects treated as the natural monuments.
