The Mayan Ruins at Uxmal, Yucatan, Mexico. The ruins of the ancient Mayan city, Uxmal, go from impressive to unbelievable when you consider that these large stone structures were constructed without the use of wheels. It makes the myth surrounding the Pyramid of the Magician—that the structure was conjured by a dwarf over a single night—seem comparably plausible. Photographed using a high-dynamic-range process.
