1. Bermuda Triangle
In 1964, an author coined the phrase “The Deadly Bermuda Triangle” after a number of aircrafts went missing in the area roughly bounded by Miami, Bermuda, and Puerto Rico. While popular culture attributed disappearances to paranormal activity, a 2013 study of the 10 most dangerous waters in the world for shipping did not list the Bermuda Triangle.
2. Area 51
This U.S. Air Force installation is 80 miles northwest from Las Vegas and was recently declassified as a testing grounds for the U-2 and other spy planes.

7. Mariana Trench:
Deeper than Everest is tall and five times longer than the Grand Canyon, the Mariana Trench is the planet’s deepest point. And while many have scaled Everest, only four have descended into its watery depths.
8. Easter Island:
This Polynesian island in the southeastern Pacific Ocean is known for its 887 human figures carved out of rock. What they represented may have varied, either constructed for deceased ancestors or for the embodiment of chiefs.
9. The Great Pyramid of Giza:
Built as a tomb for an Egyptian pharaoh, this pyramid was the world’s tallest man-made structure for over 3,800 years. Various construction techniques — many contradictory — have been proposed about how the structure came to be.
This southernmost continent is the coldest, driest, and windiest place on Earth. There are no permanent residents, but anywhere from 1,000 to 5,000 scientists are conducting research throughout the year.
Polar explorer Ben Saunders and his partner Tarka L’Herpiniere will attempt to be the first people to complete the 1,800-mile return journey from the coast of Antarctica to the South Pole, which British Royal Navy Captain Robert Scott famously attempted in 1910–1912.
