Boka Kotorska
English:
The Bay of Kotor, in Montenegrin Boka Kotorska or simply Boka, is a nearly 30 km long, fjord like, winding bay, seamed by steep mountainsides. It's composed by three basins connected by two narrow straits. The basins are Herceg Novi, Tivat and Morinj-Risan-Kotor.
Due to the surrounding high mountains the bay is often considered as the southernmost fjord in Europe. But fjords are created by glacial processes, whereas Boka Kotorska is part of a ria coastal system. A ria is a coastal inlet, usually narrow and long, which was created by a river and afterwards flooded by the sea.
The area of Boka Kotorska is divided in three geomorphological regions (see map below): The Adriatic-Ionian Zone build up by Cretaceous limestones, anhydrites and dolomites, and Eocene-Oligocene flysch deposits. Thrust-folded over this tectonic unit is the Pindus-Cukali Zone consisting of Triassic flysch deposits and carbonates, Cretaceous limestones and Paleocene flysch. This zone is overthrust by the High Karst Zone made mainly of Mesozoic limestone and dolomites with thickness reaching several kilometers due to reverse faulting and overthrusting that duplicate the carbonate series.
To log this earthcache, perform the followings tasks and send us your result. You can log immediately after sending. You will get an answer in any case.
1. Is Boka Kotorska a fjord? Explain in your own words how Boka Kotorska was created.
2. At the cache location you are at a border of two geomorphological regions. Please name them and describe the differences you see on site (view direction bay and behind you).
3. (optional) Pictures of your stay are highly welcome, but that's no obligation. It's just to please us and other cachers ;-) Be creative.
Crnogorski:
Bokokotorski zaliv, u Crnoj Gori Boka Kotorska ili jednostavno Boka, dug je gotovo 30 km, kao fjord, vijugava uvala, obrubljena strmim brdima. Sastoji se od tri bazena koja su povezana uskim uskim prolazima. Bazeni su Herceg Novi, Tivat i Morinj-Risan-Kotor.
Zbog okolnih visokih planina, zaliv se često smatra najjužnijim fjordom u Evropi. Fjordovi su stvoreni glacijalnim procesima, dok je Boka Kotorska dio rijskog obalnog sistema. Ria je priobalno ušće, obično usko i dugačko, koje je stvorila rijeka i nakon toga poplavljeno morem.
Područje Boke Kotorske podijeljeno je na tri geomorfološka područja (pogledajte mapu ispod): Jadransko-jonska zona izgrađena od krednih krečnjaka, anhidrita i dolomita, te eocensko-oligocenskih flišnih naslaga. Prevučen preko ove tektonske jedinice je zona Pindus-Cukali koja se sastoji od trijaskih flišnih naslaga i karbonata, krednih krečnjaka i paleocenskog fliša. Ova zona je preplavljena zonom Visokog krasa, koji se uglavnom sastoji od mezozojskog krečnjaka i dolomita, a debljina seže do nekoliko kilometara zbog obrnutog rasjedanja i prevrtanja koje dupliraju karbonatne serije.
Da biste prijavili ovaj zemaljski keš, izvršite zadatke koji slede i pošaljite nam svoj rezultat. Možete se prijaviti odmah nakon slanja. Odgovor ćete dobiti u svakom slučaju.
1. Da li je Boka Kotorska fjord? Objasnite vlastitim riječima kako je stvorena Boka Kotorska.
2. Na lokaciji keša nalazite se na granici dva geomorfološka regiona. Molimo vas da ih navedete i opišete razlike koje vidite na licu mesta (pogled u smeru i iza vas).
3. (opcionalno) Slike vašeg boravka su veoma dobrodošle, ali to nije obaveza. To je samo za zadovoljstvo nama i drugim cachers ;-) Budite kreativni.
