Descrizione

Morfologia

The entrance is wide and has vegetation. A 23-metre vertical leads to a 9-metre shaft and to a chamber filled with blocks; at its base, a dig gives access to a new 17-metre shaft and to two other new digs that lead to further verticals down to -76 metres. Later work indicates new depths down to -306 metres.
