So whether something is a cave or not depends on the direction of the gravitational force. Isaac Newton has a lot to answer for.

At what point does the surface depression magically transform into a cave? I vouch that the depression/pit remains part of the surface of the planet; it is not a cave if daylight can reach it.
It has major relevance to the CRoW debate because a cave needs to be legally defined; how else can it be defined other than by saying a cave commences where daylight ends?

Aubrey said:I do not think caving can be called an open air activity because 'open air' implies fresh air.
Some caves frequently have bad air or very high levels of CO2 and there is a lot of documentation about Radon in caves. If the caves were open air then these gases would be immediately dissipated into the atmosphere.
