Geocache Description:





Stone spheres





There is a narrow track of sandstones with visible sphere parting in the northwest part of Slovakia in the territory between Klokocov village and Moravsko-slezske Beskydy edge. From geological point of view this land is the west part of Flysh area. These groups of strata were created between Cetraceous and Eocene era.

The spheres are found primarily in the desert sandstone quarry close the Milosova – Megonky settlement, pudding-stone face Klokocovske skalie and also on some spots in forest. Stone spheres are from 0,3 to 2,6 m in diameter and weight up to several tons. They are made from grit pudding-stones with rocks up to 4 cm and their face is fine-grained.

As to how the stone spheres were made, there are, as yet, no credibly explanations.

To log this earthcache you should:
• upload a picture of yourself and your GPS with some stone sphere (may be also GPS with sphere if you are alone)
Email to me the answers to the following questions:
- according which village is called sandstone from this area?
- where you can find similar stone sphere in the world?

Logs which do not meet these criterias may be deleted.




V severozápadnej casti Slovenska v priestore medzi Klokocovom a hrebenom Moravsko-sliezkych Beskýd sa nachádza úzky pruh pieskovcov s nápadnou gulovitou odlucnostou. Z geologického hladiska patrí územie k západnému úseku Flyšového pásma. Vek tohoto flyšového súvrstia je vrchná krieda až stredný eocén.

Pieskovcové gule rôznych priemerov od 0,3 do 2,6 m a tvarov od vajcovitého až po takmer dokonalý gulový tvar sa nachádzajú v stene opusteného pieskovcového lomu Milošová - Megonky, v pieskovcovo-zlepencovej stene Klokocovské skálie, alebo na viacerých miestach v lese, kde sú ciastocne vypreparované alebo ako ojedinelé gule v potokoch, vypadnuté z pieskovcovej polohy. Teleso gule je tvorené hrubozrnným zlepencom s kamienkami do 2-4 cm, povrch gule je tvorený jemnozrnnou úpravou.

Co bolo prícinou vzniku gulovitej odlucnosti? S urcitostou možno povedat iba to, že pocas jej vzniku zohrali významnú úlohu tektonické pochody v case formovania geologickej stavby západného úseku Flyšového pásma. Zdá sa, že skutocná prícina zostane i nadalej tajomstvom prírody.


Na zalogovanie nalezu tejto earthcache musite:
• odfotte sa spolu s GPS u niektorej gule (ak si sam, moze byt gula s GPS). Foto prilozte k logu.
napis mi odpovede na nasledovne otazky:
- podla ktorej obce sa nazývá pieskovec v tejto lokalite?
- kde vo svete sa nachadzaju obdobne kamenne gule?

Logy, ktore nesplnia vyssie uvedene podmienky, budu zmazane.
