The idea that you should map anything in a natural cave as "pressurised"
is a fundamentally flawed concept. The water level drops a few inches and
suddenly the "pipe" is no longer water filled or only parts of it. Other
parts of the cave will become pressurised after a rain that fills the
cave with water?
The fact that it has been approved only demonstates that our approval process
is defying reality and physics <g>
