The creation of a cenote happens
like this:
SOLUTION CAVERN - Groundwater seeps through cracks in limestone
dissolving areas of softer rock. Over time a large underground cavern
with only a thin limestone roof is created.
YOUNG CENOTE - As erosion
continues, the thin ground roof collapses, leaving an open, water-filled
hole.
MATURE CENOTE - Over
thousands of years, erosion gradually fills in the hole making
it more shallow. The Cenote of Sacrifice at Chichen Itza is in
this stage.
