Geocache Description:

The Big Ice Cave at Paradana is a typical cold trap ice cave. A huge entrance portal at the ground of a huge doline is followed by a downwards pointing huge passage. Cold air is trapped during summer and the ice stays inside the cave during the year.

The Big Ice Cave at Paradana is known worldwide due to the classical description of the inversion of the vegetation belts in its western part. The cave is 1550 m long.
In the Ice Cave ice blocks used to be cut. They were carried up to the surface in baskets and transported to Gorizia or Trieste by night. From there the ice was sold to the ships.
In the earlier days the ice was exported even to Egypt. Paradana is protected as a Natural Reserve. The Tourist society in Lokve, which is in charge of the cave, has marked a path leading to the cave.

In the SW part of the Dinaric Karst, now in the sub-Mediterranean climate, many karst features were generated at the contact of impermeable Eocene flysch with Mezozoic limestone. The flysch was tectonically partially overthrust by the older sediment cover, mostly in the western part of the so-called High border plateaus (Banjsice, Trnovski gozd, Nanos, Javorniki, Notranjski Sneznik) which extend at altitudes from 700 to 1500 m from Isonzo valley to Mt Sneznik. The Pleistocene glaciers on the Mt Golaki and Notranjski Sneznik and periglacial climate around them left dense deep potholes. With collapse of the cave roof, the Great Ice Cave Velika Paradana opened to the surface at an altitude of 1140 m. In its collapse doline is the internationally known vegetation inversion as a consequence of temperature inversion. The inverted stratification from bottom ice to mixed forest at its top was researched in the year 1905 as one of the first cases in the world. The 8 km long and 400 m deep dry valley of Cepovan on Banjsice plateau was eroded by the river Idrijca before it was captured by the Isonzo river and after the tectonics tore the transverse stratigraphical belts on both sides.
The Trnovo Forest and the neighbouring Banjšcice plateau are the most north-western spur of the grand Dinar mountains. The mountainous area of the Trnovo Forest is karst-like, with no running superficial water, full of closed hollows, hills of different height and mountains, caves, abysses, shafts and minute karstic forms: scallops, grooves, rockholes, etc. Among the most impressive karstic phenomena are the caves with permanent ice and snow. The Paradana Cave is one of the most renowned examples.
The Trnovo Forest is mainly overgrown with beech and fir trees (Abieti-fagetum dinaricum). The highest point is Mt. Mali Golak
(1495 m a.s.l.). The Trnovo Forest has two natural reserves: Paradana with the natural monument of the Big Ice Cave and
Mt. Golaki with the pine tree vale Smrekova draga and the natural monument Smrecje. Admirers of the nature can indulge themselves in many other numerous curiosities and visit monuments of the natural heritage.
