Gravity measurements in the Holštejnská Cave in the Moravian Karst
Beneš, V. ; Kadlec, Jaroslav
The Holštejnská Cave is a horizontal corridor 50 m wide, almost filled with flkuvial deposits. Gravity measurements were used to reconstruct morphology of the bottom of the cave. Based on gravity data, the total height of the cave corridor varies between 5 and 7 m and the bottom decreases to the depth of more than 15 m in the SW part of the cave.

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.
