Description
Morphology
Typical morphology of a collapse cavity. A 3-metre step and a ramp lead, at their start, to a fork. An ascending branch leads to a wide gallery with a low ceiling. The other, descending, leads to a narrow gallery where two parallel 4-metre shafts are found that reach the point of maximum depth. At the beginning and end of this gallery there are passages between blocks that connect with the upper branch.
Speleothems
The floor of the wide gallery is covered with small gours and pisolites.
