"El Castillo," a Mayan temple on the Yucatan Peninsula in Mexico, with a mysterious "light beam" emerging from the top.

When Hector Siliezar visited the ancient Mayan city of Chichen Itza with his wife and kids in 2009, he snapped three iPhone photos of El Castillo, a pyramid that once served as a sacred temple to the Mayan god Kukulkan. A thunderstorm was brewing near the temple, and Siliezar was trying to capture lightning crackling dramatically over the ruins.

In the first two images, dark clouds loom above the pyramid, but nothing is amiss. However, in the third photo, a powerful beam of light appears to shoot up from the pyramid toward the heavens, and a thunderbolt flashes in the background.

Siliezar, who recently shared his photographs with occult investigators, told Earthfiles.com that he and his family didn't see the light beam in person; it appeared only on camera. "It was amazing

!" he said. He showed the iPhone photo to his fellow tourists. "No one, not even the tour guide, had ever seen anything like it before."
