Naučná stezka Zlatý kůň

Quarry Na Kobyle

Massive pinkish Slivenec limestones which were mined in the quarry used to build the peripheral area of the limestone cliff of Zlatý kůň. Slivenec limestones created together with cliff Koněprusy limestones during Variscan orogeny a compact, uneasily foldable unit. Older limestones of the lochkovian formation and silurian limestones of the požár formation were slided onto this unit from north. This slide took part along a distinctive defect – Očkov rearrangement. Length of the slide is estimated to approximately 1 km. The slide area of the tectonic structure is distinctly shown in the upper part of northern quarry wall. Some karst phenomena were uncovered through mining. The cave Zlomená sluj has its upper floor developed according to the slide area of the Očkov rearrangement. In the cave Chlupáčova sluj important discoveries of mammal bones from the last interglacial age were made (cave lion, hyaena, bear, steppe horse, rhino). Stone tools and bones of wild animals from the older Stone Age belong to one of the oldest man traces in the territory of Český kras. On the quarry wall at the adit estuary there is a commemorative board which reminds on karst explorer Jaroslav Petrbok (1881–1960) who devoted himself to the research of Chlupáčova sluj. Abandoned quarries provide refuge to many rare plants and animals. On moister places arises endangered dandellion Taraxacum bavaricum which does not grow elsewhere in the territory of Český kras. Its occurrence here is enabled through the fact that there is not a deeper soil layer at the bottom of the quarry which therefore does not grow over (so called blocked ecological succession). This fact is also supported by the visitors of the territory who tread down the green. At the end of summer blossoms here gentian Gentianopsis ciliata.
Overgrowing quarry walls with frequent rock terraces are a suitable nesting place for the most frequent falcon beast of prey in Czech republic – common kestrel (Falco tinnunculus) – as well as for Eurasian eagle-owl (Bubo bubo), the biggest European owl.
