This mountain is located in the village of Predjama, approximately 11 kilometres from the town of Postojna and 9 kilometres from Postojna Cave.
What is the Karst?
The karst is a geomorphological structure resulting from the hydrochemical and hydraulic erosion of all soluble rocks, mainly carbonate rocks, mainly limestones. Karstic structures are also found in evaporite chlorides. Karstic processes, known as "pseudokartic" processes, may also develop in some rocks other than carbonate rocks or evaporite chlorides.
In addition, morphologies analogous to those resulting from karstic or pseudokartic processes are found in certain glacial zones: inlands, glaciers The glacial structures or the corresponding geomorphologies are thus called glaciokarsts, cryokarsts or thermokarsts.
The karsts mostly present a tormented landscape, a hydrographic network mainly underground (like rivers) and a subsoil excavated numerous cavities: ruiniform reliefs, losses and resurgences of streams, caves and chasms.
Rocks affected by karst phenomena:
- Limestone

The Earthcache
At Ground Zero you can observe the Predjama Mountain and the entrance of the cave.
To log this earthcache send us the answers of the following questions by email:
1. Describes by your words what is karst.
2. Do you see any kind of krast on this mountain? Explains.
3. From this location, what is the format of the cave entrance?
4. Take a photo of yourself or your nickname showing the place or the surrounding landscape (Mandatory task from July 22, 2025).
According to the January 2013 guidelines: After sending the answers by email you can log it, and upload the photo, if there is any problem we will contact you. If you do not send us the answers, or do not upload the photo, your log will be deleted.
Ta planina se nahaja v vasi Predjama, priblizno 11 kilometrov od mesta Postojna in 9 kilometrov od Postojnske jame.
Kaj je Kras?
Kraška je geomorfološka struktura, ki izhaja iz hidrokemične in hidravlične erozije vseh topnih kamnin, predvsem karbonatnih kamnin, predvsem apnencev. Kraške strukture najdemo tudi v evaporitnih kloridih. Kraški procesi, znani kot "pseudokartični" procesi, se lahko razvijejo tudi v nekaterih skalnih kamninah, razen karbonatnih kamnin ali evaporitnih kloridov.
Poleg tega so v določenih ledeniških predelih podobne morfologije, podobne tistim, ki so posledica kraških ali psevdokartičnih procesov: otoki, ledeniki. Ledijske strukture ali ustrezne geomorfologije se tako imenujejo glaciokarsts, kriokarstov ali termokarstov.
Kraški večinoma predstavljajo mučeno pokrajino, hidrografsko mrezo, ki je večinoma pod zemljo (kot rekah), in podzemlje izkopavajo številne votline: ruševine, izgube in ponovitve potokov, jam in jame.

Earthcache
V pritličju lahko opazujete Predjamsko goro in vhod v jamo.
Če se zelite prijaviti na to zemeljsko pot, nam pošljite odgovore na naslednja vprašanja po elektronski pošti:
1. Po vaših besedah opisuje, kaj je kraški.
2. Ali vidite kakšno krast na tej gori? Pojasnjuje.
3. Na tej lokaciji, kakšna je oblika vhoda v jamo?
4. Fotografirajte sebe ali svoj vzdevek, na kateri je prikazan kraj ali okoliška pokrajina (obvezna naloga od 22. julija 2025).
V skladu s smernicami iz januarja 2013: Ko odgovore pošljete po e-pošti, jih lahko zabeležite in naložite fotografijo. Če pride do kakršnih koli težav, vas bomo kontaktirali. Če nam odgovorov ne pošljete ali ne naložite fotografije, bo vaš dnevnik izbrisan.
