	The Zacatón Cenote (in the Money/Politics "How Many Countries in the World" section) - Cenotes are karst formations which occur when underground water etches away at limestone bedrock to form enormous subterranean caverns.  Eventually the cavern roofs collapse leaving deep circular rock pools.  The word cenote is a Spanish rendering of the Mayan word d'zonot which means literally "a hole in the ground"...
