Summary of site:
These two features are on the underground course of the Sruh Croppa River. McGovern’s Sink is a rubbish-filled shake hole which no one has yet had the stomach to dig. Freda’s Hole is a walled shake hole to the north east surrounded by trees. A climb down the north side ends on sloping rubble that descends through a hole on the south side into a chamber to the west with a further inclined slope leading into a narrow passage. A muddy crawl through two small chambers emerges at the base of Peg Leg Pot, about 8m from the surface.
