The deep cave system has an overhanging cliff that creates a rock shelter at the entrance facing the river.

Excavations in the 1980s carried out by archaeologist Paul Ossa and a team from La Trobe University found stone artefacts, and other signs of occupation that were dated to almost 20,000 BP.

Vertebrate fauna remains are abundant but mostly of non-cultural origin, representing animals that used the cave at times it was vacated by humans.

[3] The artefact assemblage is similar to that at the nearby Cloggs Cave in Buchan, and in conjunction with Birrigai in the ACT they represent a general signature of human occupation and resource exploitation of the southeastern uplands during the Pleistocene.

In comparison, southwestern Tasmanian Pleistocene sites appear to have a different signature of cave occupation and the primacy of a single vertebrate resource.
