A British-led
caving expedition to the
Zagros Mountains in 1971 led to the discovery of the cave. The team returned the following year and passed their previous limit, but to their great disappointment, the cave
sumped almost immediately at a depth of 751 m and could be explored no further. To be "Ghar Paraued" became a term used in British caving for a small, disappointing breakthrough following the great effort to discover new passage. ==References==
