Description

Morphology

There are two entrances that reunite at a fixed point. Right at the bottom there is also a fissure that would likely be tight even when exhaling.

Progression

After the two entrances reunite comes the hole: you simply slide down it. It is important to turn your head toward Czechia, toward where the fissure is narrow; on the other side there is a deep hole that you fall into without a rope. Then it continues steadily downward. The final chamber is reached by squeezing through with a stone at your back.
