Past this sump lie several more rooms connected by sumps, the first of which contains magnificent formations and is apparently airtight - no matter how high the stream is, the rooms will never fill with water. However, the current owners of the cave have banned cave diving since the death of diver Roberta Swicegood in the cave in June 1988; even if diving was permitted, even a skilled cave diver likely could not pass the first sump, since debris has accumulated and visibility is close to zero.
