The "red-rose" city of Petra stands as one of the most glorious and mysterious archaeological sites on earth. Created over 2,500 years ago, the ornate Petra cityscape was literally carved into the rose-colored walls of Jordan's Shara Mountains. The builders of Petra, the Nabataeans, were thought to be some of the wealthiest people ever to inhabit the Middle East, but they, along with their riches, simply vanished. What was Petra and could the Arabian site be still hiding precious treasure?

In the Bolivian Andes, a sprawling ancient city rests 13,000 feet above sea level. With its giant, freestanding monoliths and grand design, Tiwanaku has long been compared to Stonehenge.

The Maya of Central America were the greatest pyramid builders of the ancient world. The Egyptians built less than a 100 pyramids--the Maya built thousands. But what was the significance of these towering structures? Determined to solve the meaning of the Mayan pyramids, host and explorer Josh Bernstein sets out on a remarkable journey that takes him from the great Mayan cities of Southern Mexico to the hinterland of Guatemala. Josh explores ancient tombs, dives in flooded caverns, and shoots whitewater rapids. Finally, he reaches a secret place in the high jungle of Guatemala where a mountain, a cave, and a river converge. It's here, according to the Maya, that the world was born, and it's this mystical place upon which all Mayan pyramids are modeled.

Queen Nefertiti was once the most beautiful and powerful woman in Egypt, renowned throughout the ancient world. But she vanished without a trace, lost to the sands of Egypt for more than 3,000 years. Only in the last century did archeologists discover that this legendary queen really lived at all. Since then, though, only fragments of her story have emerged. Host Josh Bernstein, an explorer and survival expert, is determined to put the pieces together and uncover the true story of Queen Nefertiti. Who was this mysterious woman? Why did she disappear? And can her mummy still be found today? To find out, he'll follow a trail of clues into Egypt's most sacred and secret places, exploring dark tombs and coming face-to-face with the truth of at least one ancient mummy's identity.

It was a fable that fueled a thousand fevered explorations into the mountains and rainforests of South America. The mere idea of El Dorado--a city of gold buried in the jungle--fired the imagination of Spanish conquistadors for centuries. But when no city appeared, so the legend faded. Now explorer and survival expert Josh Bernstein begins the search anew. The recent find of a remarkable document has given new life to the search for El Dorado. Eager to follow up on these latest developments, Josh throws himself into an exciting journey that takes him from the icy waters of Lake Titicaca in Southern Peru, to the frozen Altiplano of the high Andes, then deep into the Amazon jungle as he struggles to discover the truth, once and for all, behind the legend of El Dorado.

The mystery of the 10 Lost Tribes of Israel has fascinated people through the ages. Explorers claim to have discovered evidence of the ""lost tribes"" all over the world, from Australia to Siberia, but few if any such claims have been backed up by solid evidence. But now a provocative possibility about the whereabouts of one of the tribes has emerged--and it's 4,000 miles from Israel--in Southern Africa. Host and explorer Josh Bernstein retraces the amazing journey that the Lemba people claim they made centuries ago. It stretches from the heart of modern South Africa to the ancient stone cities of Zimbabwe...and then onto the shores of the Mediterranean and the city of Jerusalem. And the evidence for this journey is more than anecdotal. As Josh discovers, recent DNA studies point to the Lemba's true origin in the Middle East.

For centuries, adventurers, and archeologists--the devout and determined, and even Indiana Jones--have all searched for the Bible's most sacred lost treasure: the Ark of the Covenant. Yet, despite all its fame, it mysteriously disappeared from the pages of history tens of centuries ago. How could something so powerful and holy simply vanish? That's what host and adventurer Josh Bernstein is determined to find out when he follows a trail that starts where the Ark's story begins--on Mount Sinai. Next, he explores a secret maze beneath Jerusalem's streets, and visits Deir es Sultan, an Ethiopian monastery located on the roof of the Church of the Holy Sepulchre. In Ethiopia, he climbs up a sheer cliff to reach Debre Damo, one of the country's most ancient monasteries, and travels across Lake Tana to the place where some say the Ark is kept today. But how close can he get to this mighty and mysterious treasure?

Join Josh Bernstein as he sails a Viking ship from Denmark to America and tries to determine for himself if the Vikings really beat Christopher Columbus to America.

Of all the rulers mentioned in the Bible, King Solomon was purportedly the wisest...and the richest! The reason? His access to vast quantities of gold. According to the Bible, the source of his legendary wealth was the goldmines located in the mysterious land of Ophir. Yet, what the Scriptures can't tell us is where Ophir might be found today.
