Velebit Caves
The Velebit mountains of Croatia have several deep caves with some of the world's largest subterranean vertical drops. The "Lukina jama" cave is 1431 m deep (2013), the deepest cave in Croatia and 17th deepest cave in the world and the deepest cave in southeast Europe.Radovan Radovinovič, The Croatian Adriatic Tourist Guide, pg. 143, Zagreb (1999), At its foot, there are ponds and streams including one of the largest known colonies of subterranean leeches ('' Erpobdella mestrovi''), which has been ascertained to represent a new species, genus and also family. Other species discovered in the system, include the air-breathing land snails '' Zospeum tholussum''. Like Lukina jama, Slovačka jama, Velebita and Meduza are also located at the " Hajdučki i Rožanski kukovi" special reserve, a dedicated part of the Sjeverni Velebit national park. Other notable caves include the "Slovačka jama" ('' Slovak pit''), (1,320 m deep), "Velebita" (1026 m deep with underground free fall ver ...

Sjeverni Velebit
The Northern Velebit National Park () is a national park in Croatia that covers 109 km2 of the northern section of the Velebit mountains, the largest mountain range in Croatia. Because of the abundant variety of this part of the Velebit range, the area was upgraded from a nature reserve in 1999, and opened as a national park in September the same year. The whole of the Velebit range is a "nature park", a lesser conservation category. Another national park on Velebit is the Paklenica on its southern side. In 2017, the beech forests within the national park were added to the UNESCO World Heritage Site known as Ancient and Primeval Beech Forests of the Carpathians and Other Regions of Europe because of their testimony to the ecological history of forest dynamics within Europe since the last Ice Age. The park The park reserve is protected and visitors are restricted to designated trails. Inside the reserve is the ''Visibaba'' ( Galanthus) botanical reserve, with an abundance ...

Limestone Caves
Limestone is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limeston ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caves Of Croatia
Caves or caverns are natural voids under the Earth's surface. Caves often form by the weathering of rock and often extend deep underground. Exogene caves are smaller openings that extend a relatively short distance underground (such as rock shelters). Caves which extend further underground than the opening is wide are called endogene caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganisms, pressure, and atmospheric influences. Isotopic dating techniques can be applied to cave sediments, to determine the time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speleology
Speleology () is the scientific study of caves and other karst features, as well as their chemical composition, composition, structure, physical property, physical properties, history, ecology, and the processes by which they form (speleogenesis) and change over time (speleomorphology). The term ''speleology'' is also sometimes applied to the recreational activity of exploration, exploring caves, but this is more properly known as ''caving'', ''potholing'' (British English), or ''spelunking'' (United States and Canadian English). Speleology and caving are often connected, as the physical skills required for ''in situ'' study are the same. Speleology is a cross-disciplinary field that combines the knowledge of chemistry, biology, geology, physics, meteorology, and cartography to develop portraits of caves as complex, evolving systems. History Before modern speleology developed, John Beaumont (geologist), John Beaumont wrote detailed descriptions of some Mendip Hills, Mendip c ...

Pitch (vertical Space)
In climbing, a pitch is a section of a climbing route between two belay points (or belay stations), and is most commonly related to the task of lead climbing (going up), but is also related to abseiling (going down). Climbing on routes that require only one pitch is known as single-pitch climbing, and climbing on routes with more than one pitch is known as multi-pitch climbing (where the number is large, it can be big wall or alpine climbing). Modern climbing ropes are typically in length, which sets the theoretical maximum length of a 'pitch', however, other factors mean that the average pitch on a multi-pitch route is circa in length. Advanced climbing techniques such as simul climbing can materially reduce—and even completely remove—the need for 'pitches' on a multi-pitch climbing route. The term is also used in caving. Description In lead climbing — either in rock climbing, mountaineering, and ice climbing — the term 'pitch' describes the length of a section ...

Slovakia
Slovakia, officially the Slovak Republic, is a landlocked country in Central Europe. It is bordered by Poland to the north, Ukraine to the east, Hungary to the south, Austria to the west, and the Czech Republic to the northwest. Slovakia's mostly mountainous territory spans about , hosting a population exceeding 5.4 million. The capital and largest city is Bratislava, while the second largest city is Košice. The Slavs arrived in the territory of the present-day Slovakia in the 5th and 6th centuries. From the late 6th century, parts of modern Slovakia were incorporated into the Pannonian Avars, Avar Khaghanate. In the 7th century, the Slavs played a significant role in the creation of Samo's Empire. When the Avar Khaghanate dissolved in the 9th century, the Slavs established the Principality of Nitra before it was annexed by the Great Moravia, Principality of Moravia, which later became Great Moravia. When Great Moravia fell in the 10th century, the territory was integrated i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Park
A national park is a nature park designated for conservation (ethic), conservation purposes because of unparalleled national natural, historic, or cultural significance. It is an area of natural, semi-natural, or developed land that is protected and owned by a government. Although governments hold different standards for national park designation, the conservation of 'wild nature' for posterity and as a symbol of national pride is a common motivation for the continued protection of all national parks around the world. National parks are almost always accessible to the public.Gissibl, B., S. Höhler and P. Kupper, 2012, ''Civilizing Nature, National Parks in Global Historical Perspective'', Berghahn, Oxford Usually national parks are developed, owned and managed by national governments, though in some countries with federal government, federal or Devolution, devolved forms of government, "national parks" may be the responsibility of subnational, regional, or local authorities.

Velebit
Velebit (; ; ) is the largest, though not the highest, mountain range in Croatia. The range forms a part of the Dinaric Alps and is located along the Adriatic coast, separating it from Lika in the interior. Velebit begins in the northwest near Senj with the Vratnik mountain pass and ends 145 km to the southeast near the source of the Zrmanja river northwest of Knin. Its highest peak is the Vaganski vrh at 1,757 m. Major mountain passes on Velebit include the aforementioned Vratnik or Senjsko bilo at 694 m.a.s.l., where the '' Josephina'' connects Senj with Josipdol; Oštarijska vrata at 928 m.a.s.l. that connects Karlobag and Gospić; and Prezid at 766 m.a.s.l. that connects Obrovac and Gračac. Velebit is characterized by its simple, solid form, stiff cliffs, the lack of vegetation on the seaward side (towards the Velebit Channel), and the wood-covered slopes of the Lika side. The basic geological characteristic of the mountains is karst; flora and fauna are abunda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
