Cenote Xkeken by Ismael Alonso (Mexico Photo Spot)

A stunning naturally formed limestone sinkhole where the walls appear to be melting. The jade waters and long stringy stalactites create a fascinating juxtaposition. In ancient times the Mayans believed these sinkholes to be portals to the underworld and would drop valuables into them as offerings. The caverns make for a unique and other-worldly photo destination. (Dzitnup, Mexico)
