The Occasional Well
The Occasional Well is a natural spring which originates in the
hydrogeological structure of the karst plateau Geravy under
Raven’s Rock (Havrania skala) rock formation in the southern
part of The Slovak Paradise National Park. It is an occasional well
– or periodic spring – with water flow varying from
zero to 45.6 L/sec. This phenomenon occurs as water from the
surface enters the ground and fills up the hollows and spaces in
the soil. When every available space is full, meaning that the
underground aquifer is saturated with water, the water surfaces
through and flows out of the natural spring.

History of the Occasional Well
The Occasional Well under Raven’s Rock was first
described by Dionýz Štúr in 1863 and 1867.
Dionýs Štúr was a world famous geologist and
scientist who founded modern stratigraphy in Slovakia. He
determined the relationship and recorded the differences between
the Alps and the Carpathian mountains. He is also well-known for
his geological research in both Slovakia (Hron and Váh river
valleys, the Low Tatra mountains and the Spiš-Gemer
Ore-mountains) and adjacent countries (Bohemia, the Alp, Croatia).
In 1865, Dionýz Štúr made the first geological map.
Besides being a director of the Imperial Geological Institute and
the founder of the Geological Museum in Vienna, he also studied all
the geological formations in the area of former Austro-Hungarian
Empire. He wrote approximately 270 scientific papers that were
mostly published in the journals of Viennas’s Geological
Institute. He contibuted much to the development of geology in the
Central Europe and the sciences of geology, geography and botany in
Slovakia.

The Slovak Paradise National Park
Slovak Paradise National Park (in Slovak:
Národný park Slovenský raj) is one of the
nine national parks in Slovakia, situated in East Slovakia. The
National Park protects the area of the Slovak Paradise mountain
range, which is located in the south-east of the High Tatras in the
north-eastern part of the mountain range of Slovenské
Rudohorie. It spreads over an area of 19 763 ha and its buffer zone
covers 13 011 ha. It straddles the districts of Brezno, Poprad,
Roznava and Spisská Nová Ves and is best typified by its
impressively deep gorges and canyons, 150 – 450 m deep,
created in limestone and dolomite by water currents. The best known
gorges include Suchá Belá, Piecky, Sokol and Kysel with
numerous waterfalls. The highest point is Mt. Javorina (1186 m).
Almost all the area is covered by limestone beech and spruce
forests. In Slovak Paradise there are almost 200 caves and
precipices; the ice cave, Dobsinská ladová jaskyna,
listed by UNESCO, has been open to the public since 1972 and in its
vicinity is a nature reserve with various rare fauna species. In
1972 a 21-km-long cave called Stratenská jaskyna was
discovered, the longest and largest cave in Slovakia. At an
altitude of 1153 m, to the north of the village of Stratená,
visitors can also find a famous rock formation known as
Raven’s Rock (Havrania skala).

Obcasný pramen
Obcasný pramen vyverá z dolomitových souvrství
hydrogeologické struktury planiny Geravy. Jde o tzv.
obcasný výver - periodickou vyveracku s výverem od 0
do max. 45.6 L/s. O existenci pramene se vedelo jiz pred více
nez 130 lety. K obcasnému výveru vody dochází
pri vysokém nasycení podzemních prostor v
srážkove bohatých obdobích. K samotnému
výveru vody dochází po naakumulování vody
v podzemních systémech dutin a prostoru napojených
na výver "násoskovým" zpusobem.
Pro
