When you think of natural disasters, you usually don't think of sinkholes, but in 2010 a Guatemalan sinkhole killed 15 people. What's the term for a sinkhole that exposes groundwater underneath?

A cenote forms when limestone beneath the surface of the earth dissolves and collapses, revealing a source of water underneath. Cenotes are fairly common in the Yucatan peninsula of Mexico, where the ancient Mayans used them to make sacrifices to their gods.
