A state-managed sinkhole pool near Tantanoola that is the second natural entrance to the Tank Cave system. CDAA Cave-rated divers may enter to 13 m in the phreatic passage; deeper is for Advanced Cave divers.
Fossil Cave, long known as the Green Waterhole, is a small pond that opens into a broad chamber floored with dark silt, with a second small pool and chamber at the far end. It sits on state land managed by the Department for Environment and Water and is booked through the South Australian parks booking system.
The CDAA states that a 2018 exploration connected Tank Cave to Green Waterhole, so this entrance is part of the wider Green Waterhole - Tank Cave system, including the fossil deposits at its western end.
環境
Fresh groundwater in a sinkhole pond and chamber with fine dark silt; the phreatic passage continues deeper beyond a signed point.
