Catherine (Kateřinská) Cave

Characteristics / Evolution of the Caves

DEVELOPMENT OF THE KATEŘINA'S CAVE

In total, there are more than 1,100 caves and abysses in the Moravian Karst. They were formed by gradual erosion and corrosion activities of atmospheric water and recessing of its subterranean streams in tectonically disturbed and relatively soluble layers of Devonian limestones. The Kateřina´s Cave is probably the most significant part of ancient seepages of the Punkva River, even from the times when there were no Punkva Caves. After dereliction of the Tertiary Badenian marine flooding from the Moravian Karst, significant changes occurred to the karst underground streams. The original direction of drainage to the Jedovnice hollow radically changed and karst waters began to cut the limestone massif to the Svitava River valley. This resulted, among other things, in today's largest hydrographic system of the Moravian Karst – the underground system of the Punkva River, of which the Kateřina´s Cave was once a part. In the following periods, especially in the Early Quaternary (Pleistocene), mighty breakdowns of ceilings happened in the underground, which formed today's appearance of the Kateřina´s Cave. And since it was once the underground route of the Punkva River, the existence of other large areas between it and the Macocha Abyss can be supposed. However, nobody has been able to get there so far, since the trails are cut across with a mighty tectonic failure and further progress is blocked by a dangerous and impassable cave-in.
