Pseudokarst caves in the sandstone rocks at Tisá and Rájec (Northern Bohemia)
Mikuláš, Radek
The area Tisá and Rájec is well known as an excellent example of "castellated sandstones". However, its caves, though common and interesting, have never been described in more detail. The caves occur often in upper parts of rock pillars, therefore, most of them are accessoble only by climbers. The most impressive example is the "Cave of the Falcon Tower" , i. e., a systém of narrow horizontal tunnels in two levels, reaching more than 20 m in length.
