Crveno Jezero
Red Lake ( hr, Crveno jezero) is a sinkhole containing a karst lake near the city of Imotski, Croatia. It is known for its numerous caves and remarkably high cliffs, reaching over 241 metres above normal water level and continuing below the water level. The total explored depth of this sinkhole is approximately 530 metres with a volume of roughly 25–30 million cubic metres, thus it is the third largest sinkhole in the world. Water drains out of the basin through underground waterways that descend below the level of the lake floor. The deepest known point of the lake is 4 metres below sea level. The sinkhole is named after the reddish-brown colour of the surrounding cliffs, coloured by iron oxides. Like the nearby Blue Lake, it is presumed that the lake emerged when the ceiling of a large cave hall collapsed. The lake is inhabited with endemic and endangered spotted minnow ('' Delminichthys adspersus'') and Imotski spined loach The spined loach (''Cobitis taenia'') is a c ...

Sinkhole
A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are locally also known as ''vrtače'' and shakeholes, and to openings where surface water enters into underground passages known as ''ponor'', swallow hole or swallet. A ''cenote'' is a type of sinkhole that exposes groundwater underneath. A ''sink'' or ''stream sink'' are more general terms for sites that drain surface water, possibly by infiltration into sediment or crumbled rock. Most sinkholes are caused by karst processes – the chemical dissolution of carbonate rocks, collapse or suffosion processes. Sinkholes are usually circular and vary in size from tens to hundreds of meters both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes may form gradually or suddenly, and are found worldwide. Formation Natural processes Sinkholes may capture surf ...

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much earlier ...

Imotski
Imotski (; it, Imoschi; lat, Emotha, later ''Imota'') is a small town on the northern side of the Biokovo massif in the Dalmatian Hinterland of southern Croatia, near the border with Bosnia and Herzegovina. Imotski, like the surrounding inland Dalmatia, has a generally mild Mediterranean climate which makes it a popular tourist destination. Geography The town is located close to the border with Bosnia and Herzegovina, 10 km away from Posušje and 18 km from Grude. It is located 29 km away from the coast (Baška Voda). The nearest coastal town is Makarska, on the other side of the Biokovo massif. The town is located on the crossroad of D60 and D76 state roads and 20 km from the Sveti Ilija Tunnel. The A1 motorway is accessed at the Zagvozd Interchange, next to the D76 expressway. Imotski is known for its medieval fortress on the rocks of Blue Lake. Another phenomenon is the Red Lake which looks like an eye in the scenery. Both lakes are said to be connec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cave
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. 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, microorgani ...

List Of Sinkholes
The following is a list of sinkholes, blue holes, dolines, crown holes, cenotes, and pit caves. A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. Some are caused by karst processes—for example, the chemical dissolution of carbonate rocks or suffosion processes. Sinkholes vary in size from both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes may form gradually or suddenly, and are found worldwide. 21st century sinkholes * 2007 Guatemala City sinkhole – a deep sinkhole which formed in Guatemala City in 2007, due to sewage pipe ruptures. * 2010 Guatemala City sinkhole – a disaster in which an area approximately across and deep collapsed in Guatemala City, swallowing a three-story factory. * 2012 Ottawa sinkhole – Regional Road 174 at the Jeanne D'Arc interchange on September 4, 2012. * 2014 Ottawa sinkhole – at the LRT tunnelling site at Waller Street, j ...

Blue Lake (Croatia)
Blue Lake ( hr, Modro jezero or ''Plavo jezero'') is a karst lake located near Imotski in southern Croatia. Like the nearby Red Lake, it lies in a deep sinkhole A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are locally also known as ''vrtače'' and shakeholes, and to openi ... possibly formed by the collapse of an enormous cave. The total depth from the upper rim is around , while water depth varies with season. In spring, when the snow from surrounding mountains melts, it can reach , and in 1914 it reached , overflowing the southern rim. The lake is a popular destination for hiking and sight-seeing. Maximum dimensions of the lake are around , but they significantly vary due to big changes in the water level. At the end of the summer the lake may completely disappear. In 1907 a road was built descending to the lake. In 1942, an earthquake cause ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spined Loach
The spined loach (''Cobitis taenia'') is a common freshwater fish in Europe. It is sometimes known as spotted weather loach, not to be confused with the "typical" weather loaches of the genus ''Misgurnus''. This is the type species of the spiny loach genus ('' Cobitis'') and the true loach family (Cobitidae). Description The spined loach typically reaches an adult length of , although females may grow up to . Adults weigh between . Their backs feature a yellow-brown colouring interspersed with many small grey or brown scales on the spinal ridge. The scales on the belly are pale yellow or orange. The body overall is long and thin. There are 6 barbels around the mouth. Under the eyes there is a two-pointed spike, with which the fish can inflict a painful sting. Distribution and relationships It is found from the Volga River basin to France. Generally it occurs across much of temperate Europe north of the Alpide belt, with the exceptions of Ireland, Scotland, Wales and northern ...

Lakes Of Croatia
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
