The Blue Hole an example of a natural artesian well, a type of well or spring fed by water under high pressure; and of a cenóte, a collapsed cavern exposing groundwater beneath. The cavern was formed by the dissolution of the limestone bedrock by groundwater, carving caverns into the rock until the roof caved in.
