Ye with ears listen to stales.

But I leaned forward in my chair waiting, hoping, for Brother Stales to mention the object, or more accurately, the lack of objects, of my perverted affection. Maybe he forgot...

SINKHOLES

Sinkholes collapse when the watertable is lowered in places that are underlain by carbonic rock like limestone. Quarrymen pump water from quarries in order to keep the pits dry for mining. This lowers the local water table and so solution cavities, no longer buoyed up by the watermass or clayfill, suddenly collapse.

Alabaster, Alabama, until recently, held the worlds record for the deepest and widest collapse. In 1971 a sleeping farmer was awaken by the sound of a muffled Thud. The next morning he walked to his back forty and was met by a 200 foot deep hole, 400 foot wide, with a beautiful lake at the bottom that sounded out at 125 foot deep. He was a Christian man and he said, "Golly". The hole became to be know by hydrogeologists worldwide as the "Golly Hole".

I am a caver and cavers love sinkholes.
