The great Egyptian Pyramids of Giza have inspired awe and wonder and, quite likely, fierce speculation from the moment they were built. In fact, even the date of their construction has become a topic of debate. Explorer, survival expert, and host Josh Bernstein takes a hard look at the competing theories as to who really built the pyramids--and when. Archaeologists say it was the ancient Egyptians, others argue for an even older civilization. Filmed in HDTV, this fresh and engaging series digs for the truth and goes to extremes to do it! Josh examines the evidence, explores secret chambers in the heart of the Great Pyramid of Khufu, visits the first pyramid ever built, and tries his hand at ancient stone-quarrying techniques. It's a hard-won perspective, but, with the discovery of a mysterious flooded chamber deep beneath the Sphinx, Josh learns what appears to be the final truth.

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.

In 79 AD, the volcano Vesuvius exploded in one of history's deadliest eruptions, burying the city of Pompeii and other Roman towns along the Bay of Naples beneath layers of ash and pumice. Pompeii was rediscovered in the 18th century, but only recently have archaeologists and volcanologists come to understand exactly how the eruption unfolded, and why it took the people of Pompeii almost entirely by surprise. Intrigued, host Josh Bernstein visits the Bay of Naples, and learns the entire area is built on ancient volcanic rock, some of it still steaming. He climbs the world's most active volcano--Stromboli--an island near Sicily, where ""fireworks"" from the mountain are a nightly entertainment. Back at Pompeii, he searches for clues that might have enlightened the Romans to the growing threat in their midst. And he literally plays with fire as he follows the story right into the heart of Vesuvius.

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?

For all its fame, the Holy Grail remains shrouded in mystery. What exactly was it? Could it have survived to this day? Why has it inspired so many treasure seekers? To Christians, it is the holiest of objects, the cup from which Jesus drank at the Last Supper, also believed to be the chalice that Joseph of Arimathea used to catch Christ's blood as he died on the cross. Though now thought of as a goblet, the actual word ""grail"" comes to us from the Latin word gradalis--a flat dish or shallow vessel brought to the table during various courses of a meal. The story itself did not originate until medieval times, when it helped inflame the Crusaders' quest. Host and adventurer Josh Bernstein follows the Grail's trail from Holy Land to medieval French castles to a dark chapter in the Nazi saga, when Hitler financed a search for the Grail to unite a secret society of knights. On the way, Josh learns its true meaning and power.

In 1991, a pair of vacationing German hikers stumbled onto one of the most remarkable finds in the history of archaeology: the perfectly preserved body of a 5,000-year old man. What made the discovery so important was more than just his state of physical preservation, but also the period of time from which he came--the very cusp of the age between stone and steel. Host and adventurer Josh Bernstein heads for the high Alps on the Austrian-Italian border to discover the latest secrets revealed by the clothes, weaponry, and body of Ötzi the Iceman. Josh faces down a deadly blizzard, helicopters out of near disaster, and comes face-to-face with a stone-cold, stone-age killer. Along the way, he discovers that the Iceman is rewriting our ideas about the life of our ancestors at the dawn of civilization--and he learns much about the character of Ötzi!

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. Host Josh Bernstein leads us on an epic 4,000-mile journey in search of the lost gold of King Solomon--sailing across the Red Sea, plunging down a Zimbabwean gold mine, and traveling deep into the Ethiopian Bush.

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.

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.

Etched into the driest desert in the world, the mysterious lines and figures of Nazca in Southern Peru are invisible from the ground. Thought to have been made by the Nazca people, who flourished between 200 BC and 600 AD, in fact, these huge drawings were not discovered until the 1930s--and only then by commercial airline pilots who happened to over-fly them. Ever since, they have intrigued the world. Who built them, and why? Host, explorer, and survival expert Josh Bernstein takes on the secrets of the Nazca Lines, while flying micro-lites and powered para-gliders, clambering through thousand-year old irrigation tunnels, and even recreating rituals with contemporary Native Americans.

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.

On the remotest island on the face of the planet stand the massive, enigmatic stone statues of Easter Island. Who carved them? And why? Ever since Easter Island was first discovered, this tiny pinprick of land in the middle of the Pacific Ocean has baffled scientists. How did the ancients who peopled this place even find it? Host Josh Bernstein sets out to unveil the mysteries of the island and of the remarkable stone heads that its first inhabitants left behind. Delving into the world of ancient Pacific Islanders, he relearns the lost art of Polynesian navigation, recreates the techniques of Easter Island masons, and participates in dangerous ancient rituals--all to solve one of the greatest enigmas of our time: the mystery of Easter Island.

In the American Southwest, there is no more puzzling mystery than the magnificent stone cliff dwellings of Mesa Verde. Why did the Anasazi Indians suddenly move their villages to these perilous cliffs in the 13th century--and then abandon them just decades later--and seemingly disappear from history? Was it drought? Invading tribes? Or an insidious ""cancer"" from within that may have caused them to turn to fierce warfare and even cannibalism? In search of answers, our host, the intrepid explorer and survival expert Josh Bernstein, travels from Mesa Verde, Colorado to remote canyons in Utah where the Anasazi took refuge. Piecing together the story from both archaeologists and Native Americans, he finally ends up, in his search for the truth, in the eerie and desolate ruins of the Anasazi's greatest cultural center--Chaco Canyon.
