Proces vzniku Mucinskej jaskyne je netradicny. V dobach pred cca
20 milionmi rokov bolo okolite uzemie vulkanicky cinne. Mohutny
vybuch pravekej sopky pochoval pod niekolkometrovymi nanosmi
sopecneho popola rozlahle uzemie, porastene vegetaciou. Pod
sopecnym popolom skoncil aj statny kmen zvaleneho pravekeho stromu.
Po milionoch rokov skamenenim sopecneho popola vznikol tvrdy tuf.
Na druhej strane, kmen stromu zuholnatel a potom, ako sa k nemu
dostala voda, postupne vyerodoval z tufu. Tak vznikol zaklad
Mucinskej jaskyne. Ta sa casom rozsirila vplyvom prirodzeneho
procesu erozie tufu a az v roku 2004 bola preskumana miestnymi
jaskyniarmi.
Neklamnym potvrdenim hypotezy o vzniku jaskyne su zuholnatene
zvysky konarov pravekeho stromu, ktore sa stale daju najst na
stenach jaskyne (napr. hned pri vchode vpravo dole). Okrem toho, v
jaskyni a blizkom okoli su odkryte tufove vrstvy, v ktorych boli
najdene skameneliny pravekej vegetacie - vetiev, stoniek, listov.
Ak sa poobzerate okolo seba, mozno sa vam podari nejaku tu
skamenelinku objavit. Vraj sa nejake skamenele listy daju vidiet na
zadnej stene jaskyne, ale priznam sa, neoveroval som to.
Vstup do jaskyne je na vlastne nebezpecenstvo.
Sopecny tuf je velmi krehky, ale dost tazky ked spadne na hlavu,
tak si davajte pozor.
Prosim odolajte pokuseniu a nelikvidujte
tufove vrstvy v snahe najst skamenelinu. Tuf zvetrava aj sam a
niekedy sa da najst pekna vec v kuskoch, ktore sa samovolne
oddeluju zo stien.

The process of Mucin Cave origination is quite uncommon. 20
million years ago, the surrounding area was volcanicly active. The
eruption of nearby volcano covered a large area by thick layers of
volcanic ash. The ash covered a lot of then-subtropical vegetation
and, in particular, one fallen tree trunk, which later gave birth
to the cave. After millions of years, the volcanic ash hardened and
became volcanic tuff. On the other hand, the tree trunk
carbonified. Later, after water found its way to the carbonified
tree, it eroded out of the tuff, creating what was to become the
Mucin Cave. The cave naturally expanded by tuff erosion, and only
in the year 2004, it was inspected by local speleologists for the
first time.
You can still find remnants of the carbonified tree's branches
in the cave walls (e.g. right-bottom at the entrance). Moreover,
the tuff beds are uncovered in the cave and its close surroundings.
They carry a lot of fossils of prehistoric vegetation - leaves,
branches, stems. If you carefully look around, you might find some
of these. Allegedly there are also some leaf imprints preserved on
the back cave wall, but I didn't check that.
Beware, entry to the cave is at your own risk!
The volcanic tuff is quite fragile, but heavy if it falls upon your
head, so please be careful.
Please resist the temptation to break up the
tuff beds in order to find fossils. The tuff is weathering
naturally and you can sometimes find a nice piece in the fragments
fallen off the walls.
