The Great Lakes of North America are the largest expanse of fresh water on the planet. Searching for clues of their formation, our geologists delve deep into an underground salt mine, investigate a fossilized coral reef, climb an Alpine glacier, and dive to the bottom of Lake Superior. They find evidence of an ancient tropical sea, a mighty rift that almost tore the continent in half, and a mile high ice sheet that repeatedly carved its way across North America. And as the lakes settle to their current levels, cascading over Niagara Falls, we find that their evolution is far from over.

It's down to the final 4 days and Troy's road to the crown takes an unexpected turn. A good friend and fellow hunter has passed away. When his long-time helper asks Troy to help fill their remaining tags, Troy has a dilemma. If he helps, he will have to put his own tags on hold and with so little time left in the season, it could mean that he doesn't tag out. R.J. and Jay Paul are working tirelessly to fill their bayou-best 500 tags this season. As the season enters its final days, R.J. is more focused than ever before. Willie and Randy are embarking on their last day as partners this season. Starting tomorrow, Randy has to move onto the next commercial hunting season, fishing for buffalo fish. Determined to go out with a bang, the brothers are hunting in a favorite childhood spot. Bruce's longtime sidekick Tyler isn't feeling well. With the season ticking away quickly, Bruce has no choice but to focus on the hunt, but it isn't long before worry for Tyler becomes too great to ignore.

Troy is in a tough situation. After a fellow hunter passed away, Troy agreed to help fill his tags for the community, putting Troy's on hold. Now, the reigning king faces an uphill battle to finish his new tags and get back to his own before time runs out. R.J. and his son Jay Paul are gunning for the best season on record, and the duo's been moving at a hectic pace. Now, it seems the grind has finally caught up with them. With only 3 days left to hunt, exhaustion sets in for R.J. Joe and Tommy are in great position as they enter the home stretch. With only 25 tags to fill in 3 days, the crew is focusing on big gators. As they run their lines, they quickly discover that a monster gator is lurking nearby--one with prime waterfront property. Glenn and Mitchell are busy doing what they do best. Today, the boys are looking for garfish...but as things often go with the brothers, the day leads to unexpected places.

It's the home stretch and swampers have the finish line in sight. Joe and Tommy are in a good position. At the end of the season, Joe usually hunts a reliable honey hole to get him across the finish line. But this year Tommy wants to lead the way to a new spot...and for the first time, Joe's willing to follow. Troy is looking to make up for lost time. If he hopes to retain his crown as King of the Swamp, he has no choice but to fill 45 tags in 48 hours. R.J. and his son Jay Paul have endured a grueling pace, but with so many tags already filled, the boys have run out of fresh territory. Now, they're forced to fish depleted hunting grounds for a second time. Liz and Kristi are feeling optimistic about the final days of the season and Liz has a plan to maximize the time she has left. To fill their remaining tags, the gals are returning to Liz's daddy's favorite hot spot. All season, they have operated different boats, but now Junior and Willie have reunited to close out the hunt.

As the last day of the month-long alligator season dawns, the moment of truth arrives. Today is about one thing: tagging out before the season ends at sundown. Troy is determined to hold on to his crown. He s got only 14 tags to go, but to cement his reputation Troy wants one more monster gator...one that will make a statement to the competition. R.J. and his son Jay are down to their final tags. For this father-son duo, tagging out will mean that they ve filled a bayou-best 500 tags this season. Bruce, Ron and Tyler are facing a daunting final day. The elements have wreaked havoc on Bruce s territory all season, and after Lake Pontchartrain overflowed during a storm, brackish water has chased most gators from the area. With so few tags left, Liz and Kristi are determined to finish fast, but soon, the mood sours. A fish kill from dropping oxygen levels in the water poisons the honey hole, and with so many dead fish around, gators aren t biting.

A remarkable account of the 1,000-year quest to save real-life images, from the Arabian camera obscura to Daguerre, Eastman, and the art of photography.

The Sierra Nevada, North America's highest mountain range, contains one of the most awe-inspiring geological features on the planet: Yosemite Valley. Walled by sheer 3,000-foot granite cliffs and made from one of the toughest rocks on earth, it is home to the mighty El Capitan and iconic Half Dome. Yet how this extraordinary valley formed has been the subject of controversy for over 100 years. Was it carved by gigantic glaciers or a cataclysmic rifting of the Earth?

Yellowstone National Park is one of the most dangerous geological features on Earth. In trying to uncover the processes behind Yellowstone's main attractions like "Old Faithful," geologists came to the frightening realization that Yellowstone was in fact a vast hidden super-volcano--one that is overdue for a massive eruption. Yellowstone has been on a regular eruption cycle of 600,000 years but the last eruption was over 640,000 years ago, so the next is overdue. An eruption at Yellowstone could be 2,500 times the size of the 1980 Mount St. Helens event. In the past 16.5 million years, the volcano has mysteriously moved hundreds of miles though Nevada across southern Idaho to reach its present location in Yellowstone. But even today it is still active. A swarm of 500 earthquakes hit the park early in 2009 and geologists found that the entire park is being pushed up into the air by hidden forces under the ground. Is this sleeping giant beginning to stir?

Tsunamis are one of the most terrifying forces of nature, destroying all in their path. The December 26th Tsunami is estimated to have released the energy of 23,000 Hiroshima-type atomic bombs. What are the enormous forces that generate these catastrophic waves deep on the ocean floor? With 50% of the world's population living within a mile of the sea, this episode looks at what could happen in the future. East coast cities from New York to Miami face the threat of a truly colossal wave that could be generated by the collapse of an active volcano off the coast of Africa.
