Rock spheres

kamenne_gule Sandstone or conglomerate spheres are to be found in Slovakia mainy in the Turzovská Highlands (Western Beskydy - Západné Beskydy). The largest number of rock spheres are concentrated between the main ridge of the Morava – Silesian Beskydy and a band through Klokočov - Milošová. This band is roughly 250 - 500 m wide. Most of the rock spheres are sandstone (Bukovecký sandstone, named after the locality of Bukovec pri Jablunkove where spherical separation was first noted). Besides the Milošová - Megoňky and Klokočov Rock sites it is said that there are several examples in the direction of the hamlets of Hlavica, Jelitov pri Olešnej, Kornica, and in the Kopčisko meadow in Raková - Korcháni.

First mention of the rock spheres is not that old, dating from 1995. There is an old stone quarry that lies right on the border between the Czech Republic and Slovakia. The largest and most dominant rock sphere has a diameter of 3 m and is to be found in this quarry. The actual body of the sphere is made up of coarse grain conglomerates and stones ranging in size from 2 - 4 cm, whereas the surface is made up of a more fine grain consistency. The sphere is divided by a perfect cut into two halves. Some geologists claim the spheres were created by “stresses and rotation in the ground” whereas others claim they are the result of spherical disruption of the ground.

To the west of the dominant sphere another sphere with a smooth surface was exposed; its visible part is about 25 cm big and its diameter is reckoned to be about 85 cm. More examples are to be found in the rock faces and high up on the northern face it is possible to see a “bed” of fallen spheres with an estimated diameter of 5 m. All over the region of Kysuce there are conglomerates from various materials, there are lots of exotic minerals which cannot be found anywhere around near or far. This makes the whole area very interesting from a geology point of view.

kamenne_gule Rock spheres can be seen 1.5 – 2 m beneath the present day surface as their shape is perfectly copied. Originally they lay on a horizontal plane but gradually they have been carried along by mud and sand. During orogenic process they were lifted together with the surrounding ground to today’s position and then during subsequest landslides and gradual erosion they have become exposed.

The material from which the spheres are composed has a volume weight of approx. 2 tons according to the relevant tables which means that the largest of them weighs in the region of 25 to 30 tons!
The upper semi-sphere, exposed to to the effects of water and frost, are damaged whilst the lower protected part are in good conditions with a fine grain surface. The entire area of the Turzovská Highlands are very rugged from a climatic viewpoint which more than likely as speeded up the gradual decomposition and break-up of these extraordinary objects.
Digs have gradually uncovered about 25 rock spheres of varying sizes. The largest, called Mary, is about 2.15 m diameter, whilst the most beautifully preserved one is called Hyperion. Part of the spheres from the Javorník quarry in Slovakia have rolled all the way to the Morava – Silesian Beskydy. Geologists suppose that strange formations were created by rotation in the rocks.

Places elsewhere in the world that are similar to the so far unresearched site in Kysuce are high on the list of places to see for tourists, e.g. The Navel of the World on Easter Island as well as the 4 ton rock spheres on New Zealand which lie on the ocean shore near the village of Moeraki (34 km south of Oemaru), their age is reckoned at about 4 million years.

Sandstone spheres have supposedly been discovered in south Brazil and it is said that at one time they were part of a store of spheres in the nearby Iguazu waterfall. On Costa Rica there are the largest granite spheres in the world which have a smooth polished surface, the largest of which has a 2.5 m diameter (according to some texts it is only 2.14 m which logically means that “Kysucká Mary” is the largest of all!). The Indians call them heavenly orbs and Erich von Däniken supposes that aliens left them here whereas archeologists have classed them as unresolved megalithic mysteries in the world.
What is the reason for the creation of spherical separation?? With certainty it is possible to say only this, that during their creation an important role was played by the tectonic process during the time of geological formation of the western edge of the Flysch Belt. It would seem that the real reason will remain a mystery of nature.
