The Kiss of Depth

'Caves breathe. The diurnal pressure changes from solar heating, as well as larger system-related barometric pressure shifts, account for air movement through caves. Little caves sigh. Big caves blow. Supercaves roar, sometimes with hurricane-force winds. The bigger the cave, the bigger the blow. With it's gusty breath, this one had just given Vesely and Farr the best Christmas gift either could have imagined: the kiss of depth.'

James M. Tabor relates Carol Vesely and Bill Farr finding the Cheve 'Supercave' in 1986.
