Heading to Tucson, Arizona with his son Grant, Wolter is eager to investigate a mysterious cache of crosses, swords and other relics pulled from the desert in the 1920s. One sword has a date--800 AD--written in Latin, which would suggest a group of Europeans was in the American Southwest hundreds of years before Columbus made it to America. Wolter's investigation is particularly important for one man--the grandson of the man who helped discover the items. The investigation could determine whether the artifacts are part of an elaborate hoax or part of a find that could change history.

Just east of the San Francisco Bay Area are the Berkeley Hills Walls--remnants of a massive, stone wall that stretches a distance of over fifty miles. The wall segments are up to six feet high in some places and are constructed of tightly fit limestone boulders. Scott is in intrigued by the fact that nobody knows who built the wall or even what purpose it serves. The only historical precedent for a miles-long, manmade, ancient wall is the Great Wall of China. Could ancient Asiatic explorers have made it all the way to the North American West Coast? In investigating the theory, Scott uncovers other evidence that could suggest the Chinese with their massive maritime fleet made it to the New World, using maps that were in the possession of Kublai Khan. He also discovers evidence that European explorers knew about China's epic voyages, including Italian explorer Marco Polo.

Davy Crockett was an American legend immortalized in frontier folklore for being the last one standing at the Alamo during the fight against Mexico. It was there Crockett is said to have met his heroic end. However, new evidence suggests that's not the case. An Alabama man contacts Scott Wolter about a land claim allegedly signed by Crockett--nearly 20 years after his death! As Scott investigates, he learns more about Crockett's life, membership in a secret society and involvement in the Texas Revolution at the Alamo. There, Scott discovers that the history books may be wrong when it comes to Crockett's fate and that the frontiersman's enemy, General Santa Anna, may have saved Crockett's life in a stunning twist of fate.

Scott Wolter gets a call from a man who has a mysterious stone on his property. He's convinced that it's the "Stone of Destiny"--the stone that Jacob from the Bible rested his head on when he dreamed of a stairway to Heaven. As Scott investigates, he discovers the stone was once kept with something even more valuable. It was once kept with the Ark of the Covenant and both are rumored to have been brought to America. Scott's quest for the truth leads him to a sacred site in Ireland called the Hill of Tara and to a mysterious site in Arizona where a petroglyph depicting what could be the Ark could suggest its final resting place is right here in the United States. And, as for who brought it here, a tablet inscribed with the Ten Commandments found with a series of other artifacts could suggest a likely group of candidates--the Lost Tribes of Israel.

Since the 1800s, the City of Rockwall, Texas has had a mystery it's been trying to solve.

Scott Wolter conducts a massive excavation of the wall to figure out who--or what--created this wall and the controversy surrounding it.

In 1874, Lt. Colonel George sent Custer on a scouting mission to the Black Hills area. He reportedly found something while he was there--gold. This sparked off a gold rush of settlers flooding the sacred Native American lands, which in turned sparked off a war. In response to the uprising, Custer led his forces into the ill-planned Battle of Little Big Horn, where he made his infamous Last Stand. But, before the battle, some say there was treasure to be had--gold coins, paper currency, and other valuables brought to the battlefield. So, what happened to the treasure after the battle? Piecing together a series of clues, Scott uncovers evidence suggesting Chief Two Moons who'd led the tribes against Custer, disclosed that he and his men may have looted the bodies. Only on his deathbed did he reveal it's secret location. Can Scott figure out where Custer's lost treasure might lie today?

When Scott Wolter began investigating mysterious artifacts, he started to notice one unique symbol appeared on many of them. The symbol, now known as the "Hooked X", baffled researchers who couldn't make sense of it. As Scott's investigation into the origins of the symbol unfolds, he realizes its use is unique to just two notoriously secret groups--the Knights Templar and their modern day brethren, the Freemasons. Used in secret codes, cryptic ciphers and even the alleged tomb of Jesus himself, the symbol could be the key to understanding two of the biggest mysteries of all time--exactly what the Holy Grail is, and where it's hidden today.

The Newport Tower is considered by many to be the most mysterious structure in the United States. Some people think it's a colonial era windmill or perhaps all that's left of an early water tower, but Scott Wolter is convinced it's something far more significant. Because of the archaeoastonomy and solstice illuminations that take place inside of the meticulously planned stone structure, he believes the Knights Templar came to America and built it centuries ago. Now, he's dead set on proving his theory. While planning an elaborate laser light show designed to illustrate the Tower's miraculous features, Scott discovers something else significant that ties this structure--and the Templar's modern day initiates--to one of America's most visited and most treasured icons.

Scott Wolter bushwhacks his way through the jungles of Veracruz, Mexico, as he investigates ancient artifacts that could shatter the archaeological record forever and change everything we know about our place in the universe.

In the conclusion of the two-part season finale, Forensic Geologist Scott Wolter uncovers shocking new secrets and sites, both stateside and abroad, linking the Knights Templar to cryptic symbols he believes represent one thing--a connection to Jesus's rumored bloodline. The finale plays out like a real-life Da Vinci Code drama that will have viewers on the edges of their seats!

Geologist Scott Wolter visits a Minnesota farmer who wants to investigate the possible existence of bones from a giant he unearthed in his yard. The bones raise the question of whether Vikings could have traveled all the way to America.

In Ohio, a massive mound in the shape of a serpent snakes it's way across the landscape and no one knows who built or why. Thousands of miles away, a similar serpent mound of unknown origins slinks across the landscape of Loch Nell. Could there be a connection between the two sites? As Scott Wolter investigates, he discovers evidence that both sites were constructed using the same type of archaeoastronomy. Not only that, but a number of other animal shapes have been constructed as effigies across the Midwest. In a search for answers, he discovers there could be a connection between all the sites and one of America's biggest pre-Columbian mysteries--what led to the disappearance of the people of Cahokia, America's largest city in pre-Columbian times.

Scott Wolter receives a tip that there are pyramids at the bottom of a lake in Lake Mills, Wisconsin. As he investigates, he learns local legend suggests they were built by Aztecs and over time, they've been buried as land and water have shifted. Could the Aztecs really have a connection to the American Midwest? Scott dives into the mystery, quite literally--taking a personal submarine called a Fugusub down to the depths of Lake Mills to investigate the underwater pyramids. His quest then leads him to other sites in the Midwest including the pyramids in nearby Aztalan State Park. Could it be more than coincidence that the park shares the same name as the legendary ancestral home of the Aztecs? In the end, the key to proving whether there's truth in the legend of Aztecs in America could be in the discovery of shared practices, symbols and language between north and south of the U.S. border.

The Lost Dutchman Gold Mine is the most famous lost mine in American history. It was supposedly discovered and kept secret by a German immigrant named Jacob Waltz in the 19th century, hence the "Dutchman" name. Is a true story or tall tale? The mine is rumored to lie somewhere near the Superstition Mountains in Arizona, and treasure hunters have been trying to find this mine of untold riches for more than a century. Scott Wolter decides to team up with some of these folks and offer his assistance after realizing the key to solving the mystery of the mine may lie in understanding a mysterious map carved into a series of stones called the Peralta stones. In the end, what will they find?

Forensic geologist Scott Wolter investigates artifacts featuring ancient Hebrew writing. Could they be tied to the Lost Tribes of Israel, who disappeared from the Bible in 722 B.C? Scott Wolter is bound for Tennessee to study the Bat Creek Stone, a controversial artifact with old Hebrew script found in the late 1800s. Intrigued, he then travels to Ohio to learn about an ancient mound shaped like a Hanukkah Menorah, which fascinated Thomas Jefferson. Finally, Wolter goes to New Mexico where petroglyphs feature a script that may pre-date Hebrew. All across America, Wolter finds many signs that suggest Jews made it here long ago--long before Columbus.

In the late 1500s, years before Jamestown, the English sought to create their first settlement in America at Roanoke. A party of 119 colonists came over and settled but ultimately vanished. The fate of the Lost Colony of Roanoke has eluded archaeologists, historians and North Carolina locals, but as forensic geologist Scott Wolter discovers, a series of 48 stone clues that have been largely ignored and considered frauds may in fact hold the answer to America's oldest cold case.

Before the US declared its independence, its destiny hung in the balance with the vast lands of America up for grabs to anyone willing to stake a claim. Called to examine a possibly ancient land claim, Scott Wolter is drawn into an epic quest to prove whether French fur traders were actually here on a secret mission to steal pre-Columbian land claims placed at a much earlier time. The key to this whole mystery could lie in tracking down a long-lost artifact, allegedly found with strange carvings that only those with hidden knowledge could understand. On this adventure through America's little-known early history, Scott uncovers a high stakes game of land grabbing where only the winner comes in first--and the only way to win might be to cheat.

Deep beneath the Denver Airport, conspiracy theorists say a revolutionary group that calls itself the New World Order is operating a secret base from which they'll eventually obliterate our central government. Scott Wolter is determined to get to the truth about this wild allegation. Along the way, he uncovers secrets about the New World Order that suggest the group is connected not just to one, but two mysterious sites in America where coded messages portending the end of the world continue to mystify and even terrify the general public. What's the truth behind the New World Order--and, will a tour of underground tunnels beneath the Denver Airport and the words of the only man who knows the truth offer new clues to suggest whether the NWO claims have merit or is just part of a modern day myth?

The Appalachian Mountains are a region of incredible beauty and amazing legends. One such legend tells of a terrifying giant with a 7-clawed hand who left his mark on a massive rock. This incredible rock is sacred to Cherokee people who revere the artifact for its intriguing symbols and cultural significance. Others say the symbols aren't Native, but may be connected to visitors from afar--perhaps from over the ocean or from another world. Trying to set the record straight on this controversial stone, Scott Wolter heads to Appalachia. As Scott tries to determine the age of the carvings, he discovers the stone may have strange and mystical powers. He also learns that this isn't the only massive artifact in the region--the connection between the two may lead to a "giant" conclusion.
