The surface drainage of the Jenolan River and Camp Creek is longitudinal to the structure in which the JCL represents a that is, a narrow, long limestone outcrop surrounded by non-karstic formations.In countless field examples, such bars are cut more or less perpendicularly by the hydrographic network, oftentimes through some of the most spectacular gorges.
The evolutionary interpretation of the paleokarst and the sediments in it is riddled with difficulties and leaves many basic questions unanswered.
Recent diving explorations in the Mammoth Cave, one of the Jenolan Caves, have revealed even larger, flooded cupolas—up to 100 m high—below the water table (Daniel Cove, official cave guide, personal communication, January 2004).
There is also a large breakdown (formed by the breaking down of the ceiling and walls) chamber, the Exhibition Chamber.
This also appears to be the case for the paleochannels above the present rivers and previous, now dry or sediment-filled, caves.
These unusual characteristics are part of a broader characteristic of the Jenolan Caves and their surroundings which seems to be ignored in the literature I consulted.
