The extraordinary, often bizarre treasures housed in America's museums represent wondrous chapters in history, but a physical display can tell only part of their story. Behind each artifact are amazing tales and secrets to be revealed -- tales sometimes brimming with scandal, mystery, murder and intrigue. In "Mysteries at the Museum," host Don Wildman visits a wide variety of museums across the United States, taking viewers on a sometimes shocking tour of America's past by re-examining what's been left behind. Interviews, archival footage and re-enactments bring to life the artifacts' enduring mysteries, some that have never been told before on television.

New ideas challenge basic beliefs about biblical history and the ancient world.

Travel Channel's fascination with mysteries grows with this series, adding it to a catalog that also features "Mysteries at the Castle," "Mysteries at the Museum" and "Monumental Mysteries." America's vast network of national parks -- dense expanses of virtually unexplored wilderness -- offers breeding grounds for the unsolved and unexplained. Each hourlong episode presents several perplexing stories detailing unusual events at sites including Montana's Glacier National Park, Pennsylvania's Gettysburg National Military Park, California's Shasta National Forest, and Puerto Rico's El Yunque National Forest.

Intrigued by legendary mysteries and driven by curiosity, Josh Gates is on a mission for answers. "Exhibition Unknown" chronicles his global adventures as he investigates iconic unsolved events, lost cities, buried treasures and other puzzling stories. Armed with a degree in archaeology, a quick wit and a thirst for action, Gates investigates recent developments before embarking on a detailed exploration. Whether he's trekking through Fiji in search of Amelia Earhart's remains or diving the deep seas of Panama to locate Captain Morgan's pirate ship, Gates' roughshod expeditions lead him one step closer to the truth.

This show takes viewers on a tour across the U.S. to visit mysterious and spooky paranormal hot spots. Locations vary from world-famous businesses to humble homes, each with its share of ghost sightings and unexplainable phenomena. Notable sites profiled in the series include the Liar's Club in Chicago, the Shanghai Tunnels below Portland, Ore., and the Stanley Hotel in Colorado, which provided inspiration for Stephen King's "The Shining."

Possessed by a strong curiosity and, apparently, an even stronger digestive system, host Andrew Zimmern (a chef and food writer by trade) traverses the world in pursuit of unusual regional delicacies and startling native "delights" on the menu, as he tries to ferret out the weirdest foods a location has to offer -- possibly including ferret, actually. In addition to vivid descriptions of the taste and texture of the foods he discovers, Zimmern also provides a short history of each dish. Some of the locales Zimmern has traveled to include Ecuador, Taiwan, Iceland and Minnesota (because not all "unique" foods are found in exotic locations).

There is, of course, much more to a vacation experience than hotels, sightseeing and souvenirs. For a look at what is literally on the menu, Travel Channel takes a tour of the must-see eateries across the country where a one-of-a-kind dining experience can be had. There are places that serve lip-smacking pizza, tasty deli entrees, boatloads of bacon, fresh seafood, finger-licking deep-fried dishes, juicy steaks, hot-and-spicy favorites -- the list that can whet anyone's appetite goes on and on. Each episode focuses on a specific type of food, and there's even episodic room reserved for desserts, such as ice cream and pie.

Host Camille Ford travels the country searching for dishes that have defined a particular city and created longstanding culinary rivalries. Then, she organizises a blind taste test in that city, pitting two of the most iconic eateries in a battle to settle the "food war" once and for all.

In one of the most popular series in Travel Channel's history, actor Casey Webb -- assuming the mantle from original host Adam Richman -- travels across America to sample some iconic regional dishes and take on some daunting food challenges, such as attacking a pitcher-sized bloody mary garnished with a whole fried chicken, tucking into a four-and-a-half-pound Reuben sandwich, and a choice between taking on a 151-ounce milkshake, an eight-pound sloppy joe or eating six habanero ghost chili wings. Talk about the big, the bad or the burn!

This travel series helps tourists experience cities as if they were locals, showcasing the sights of some of the world's most-popular tourist destinations with globe-trotting celebrities, who know the places well, serving as tour guides.
