Caves of Aggtelek Karst and Slovak Karst
From Conservapedia
The Caves of Aggtelek Karst and Slovak Karst in Hungary and Slovakia are known for the variety of formations and the fact that they are concentrated in a restricted area means that the 712 caves currently identified make up a typical temperate-zone karstic system. Because they display an extremely rare combination of tropical and glacial climatic effects, they make it possible to study geological history over tens of millions of years.[1]
