Geocache Description:


SLOVENSKY

Abrazne jaskyne ktore vam chceme ukazat su vo vseobecnosti zname ako najzapadnejsie jaskyne na Slovensku. V praxi sa jedna o tzv. pribojove jaskyne, zjednodusene povedane, ide o jaskyne ktorych vznik je uzko spaty s cinnostou prilivovych vln na pobrezi.

Okolie Devinskej Novej Vsi, Devinska Kobyla a svetozname paleontologicke nalezisko Sandberg boli zhruba 16 milionov rokov do minulosti omyvane morskou hladinou, resp. sa nachadzali hlboko pod nou. Viac k tejto teme vam moze priblizit nedaleka keska Sandberg - The Slovak desert.

Donedavna sa Abrazne jaskyne chybne zaradovali medzi tzv. pseudokrasove jaskyne, teda tie ktore neboli vytvorene pri krasovom procese. Prepokladalo sa totiz ze ich vznik je spojeny iba cinnostou priboja ktory mechanicky obrusoval vysoke steny skalnateho morskeho pobrezia. Dnes je vsak zrejme, ze dolezitu ulohu pri ich tvorbe zastal i proces rozpustania. Je teda pomerne tazke spravne tento typ jaskyne kategorizovat.

Samostatnu kategoriou krasu predstavuje aj paleokras. Uz z nazvu je zrejme, ze ide o stary kras. Kriteriom je teda vek krasoveho javu. Nazory na hranicu medzi krasom a paleokrasom sa roznia. Zvacsa sa za nu poklada hranica medzi tretohorami a stvrtohorami. Asi najjednoznacnejsí je vsak pripad, ak su kras, pripadne aj jaskyne, vyplnene alebo prekryte morskymi sedimentmi. U nas su takto zname prave tretohorne pribojove jaskyne pri Devinskej Novej Vsi.

Schvalne pouzivame mnozne cislo, kedze na zverejnenych suradniciach sa dostanete pred uzky vchod asi 10 metrov hlbokej verejne takmer neznamej jaskyne, ktora je mensou sestrou vseobecne znamej abraznej jaskyne v lokalite ,,Lom" (pozri waypointy). Je pravdepodobne ze tato vznikla pomocou presakovania dazdovej vody, ktora nasledne rozpustala vapnity tmel, cim by sa dala zaradit medzi krasove jaskyne, no cinnost priboja sa neda stopercentne vylucit a tak vam ju ponukame spolocne s jej pribojovou sestrou.
Navstevu jej utrob neodporucame vzhladom na vysoky stupen ochrany i znacnu zvetralost piescitych vapencov vnutri.

Pre tych z vas ktory maju moralny problem s rokmi vydupanymi chodnikmi vnutri prirodnej rezervacie a nechcu z osobnych dovodov (ci z dovodov ochrany prirody) opustit turisticku znacku - povolujeme logovanie s fotografiou a nadmorskou vyskou nameranou pri druhej z abraznych jaskyn v lokalite Lom (vid. waypointy)

ENGLISH

We would like to present you the Sea Caves which are generally known as the most westerly situated in Slovakia. The creation of such types of caves is closely linked to coastal modelling by sea waves.

The location of the Devinska Nova Ves (village), Devinska Kobyla (hill) and the worldwide-known paleontological site Sandberg were washed by the sea or laid deeply under sea level 16 million years ago. If you are interested in more information please check the nearby cache Sandberg - The Slovak desert.

Until recently the sea caves were wrongly classified as“pseudo-karst caves”, that means they were not created by karst process. It was supposed that its formation was connected only to the surge activity, which mechanically shaped high rocky walls of coastline. Today we know that the process of resolving took an important part of its creation. Therefore it is quite hard to categorize this type of cave correctly.

The “paleokarst” represents an independent category of karst. As the name discloses it is an old karst, so the age of the karst is the criterion. There are many different opinions for the line between the karst and paleokarst. The literature mostly puts the line to the age between Tertiary and Quaternary. The clearest case is, when the karst or the caves are filled or covered by sea sediments as the Tertiary surge caves near Devinska Nova Ves.

We intentionally use the plural here, because you will get to the front of narrow entrance of 10 meters deep publicly unknown surge cave by following the coordinates. The cave is the smaller sister of widely known sea cave in the “Lom” location (see waypoints). We do not recommend visiting the underground, because of high level of protection and danger of serious injury.

Ku keske

Na zalogovanie tejto kesky je potrebne splnit nasledovne podmienky:
- pridat k logu fotku vas alebo vasho GPS pred vchodom mensej z dvojice jaskyn, teda tej na ktoru ukazuju zakladne koordianty (vid. obrazok nizsie)

a poslat mailom odpovede na nasledovne dve otazky:
- aku nadmorsku vysku ste namerali pred vchodom do jaskyne
- poslite nam nazov este aspon jednej z 22 jaskyn vyskytujucich sa v Devinskych Karpatoch.

Prajeme vam prijemnu prechadzku narodnou prirodnou rezervaciou a prosime vas, aby ste pocas svojej niekolkominutovej navstevy brali ohlady na to co tu existuje uz po miliony rokov. Happy caching!


Cache

To log this cash you have to fulfill following conditions: :
- add to the log a picture of you or your GPS in front of the entrance of the smaller of the two caves, that means the one which is shown on the basic coordinates (see the picture befor)

and send answers to the following two questions via email: :
- what height above sea level did you measure in front of the entrance of the cave,
- send us the name of at least one of the 22 caves located in Devinske Karpaty.

We wish you a nice walk in national nature reserve and we beg you to respect what exists here for millions of years. Happy caching!"
