In the small town of San Bernardo in Colombia, high in the Andes, people become naturally petrified for reasons that are unknown to modern science.
This mystery was first discovered in the 50s of the last century when local cemeteries were moved by floods.
Some local citizens believe that a local diet involving guatilla and ball, two unusual fruit trees that consume that area, are responsible for mummified remains. But this explanation is less likely because the clothes are also well preserved. Others point to climate and high altitude.
This is not the first Latin American country in which there are spontaneously mummified residents. In Guanajuato, Mexico, underground gases and the chemical composition of the land are responsible for this phenomenon.
In Colombia, a mausoleum was recently built showing some of the most complete and best preserved remains.
