A group of nine Czech speleologists are
leaving for south Iran on Sunday to explore the local salt
caves, Jiri Bruthans from Charles University (UK) has told
CTK, adding that the month-long expedition is already the
seventh trip within what was originally a student project.
an expert from UK's Hydrology Institute, has taken part in
all expeditions so far.
He said that there is a world-unique salt karst with cave
systems, blind valleys and chasms in south Iran on the
Persian Gulf coast. The system includes the world's second

Malham, situated in Israel.
To beat the record, they have to discover at least 500
metres of further cavities.
Many caves still remain completely unexplored by people,
