According to a legend that dates back to the 16th century, a cache of Incan gold worth hundreds of millions of dollars is hidden off the coast of southeastern Brazil. It's known as the "Treasure of the Trinity," and it's eluded all who have sought it for 500 years. But a modern-day team of explorers follows a radical new theory to uncover its whereabouts: a remote, treacherous island where thousands of deadly vipers roam. Cork Graham leads the expedition to Queimada Grande -- known to locals as Snake Island -- armed with advanced technology to unearth complex clues and decipher puzzles that have protected the treasure for centuries. This Discovery series takes viewers along on the epic journey to one of the most dangerous places on Earth.

The producers of National Geographic Channel's hit series "Life Below Zero" are behind "Port Protection," which profiles individuals trying to survive way above the Lower 48. Surrounded by the North Pacific, Port Protection is a remote community tucked into the northwest corner of Prince of Wales Island, Alaska. The approximately 100 residents who call the rugged, unforgiving land home push the limits of survival, living an isolated and risky existence of self-reliance with no roads, government or law enforcement. However, they think the risk is worth the profound reward: a world of beauty with the security of community without the constraints of bureaucracy.

The survivalist takes people on a personal journey to face their fears and overcome their phobias.

Adventurer Ed Stafford has walked the length of the Amazon River -- he is the first person to accomplish that -- so perhaps being stranded on a desert island near Fiji without clothes, food, water and tools and attempting to survive for 60 days isn't that daunting. The only possessions he does have are cameras, and so viewers are provided a fly-on-the-wall perspective of Ed's attempts to find food, make fire, process water to drink, and build a shelter -- among many other tasks that will help him stay alive.

Discovery Channel takes the ubiquitous survival show theme to the next level by stripping it to its bare essentials. In "Naked and Afraid," complete strangers -- usually a man and a woman -- meet in a very unique way: They're stranded in a dangerous, desolate location, without food or water, and they're completely naked. Each episode follows the adventurers as they attempt to survive on their own with nothing but a personal item and the knowledge that the only prize is their pride and sense of accomplishment. Because there is no other choice, competitors quickly get to know one another -- and their surroundings -- and hope that their instincts, survival skills and intestinal fortitude serve them well.

Considered one of NASA's original space pioneers, astronaut Gordon Cooper discovered something extraordinary on a 1963 mission. While circling Earth during a 122-hour flight to detect nuclear sites, Cooper photographed more than 100 anomalies around the South Caribbean. He later believed the dark patches that appeared on the photos to be sunken ships, and while working for decades in secret, Gordon created a map that he thought could uncover treasures worth billions of dollars. Before passing away, he shared his meticulous research with longtime friend Darrell Miklos, and now Miklos is teaming with seasoned explorers and researchers to finally make good on Gordon's dream.
