Episode list

Legend has it that five hundred years ago a vast fortune in gold was hidden by the Aztecs somewhere in the American southwest. Now three families are closing in on what they believe is the location of the treasure.

The Dillman family completes the underwater dye test at Shadow Cave; in Nevada, the miners bring the Cave Rover; the Villescas family makes a new discovery that could be an important clue from an old treasure hunter.

The hunt begins to heat up when the Miners in Nevada use a smoke gun to find another entrance to this dangerous tunnel system. In New Mexico, the Villescas family has to use some crossbow ingenuity to find their way into a sketchy mine.

The Dillman family seeks answers in the mysterious Weeping Cave; in Nevada, the miners bring an expert to look at a very unusual discovery from the mine.

The Villescas family talk with an expert about whether a spur they found could tie to the Conquistadors. The Dillmans use drones to locate an important ancient symbol, which could be a map. To find out, they must repel down the side of the canyon. And in Nevada, the Miners' search is sidetracked after a potential grave site brings up questions about who else was in their mine before them.

In New Mexico, the Villescas family decide to risk everything by bringing in more heavy machinery and a full crew for one final push to find Conquistador gold. In Nevada, the Miners' years of Aztec research is threatened when the Sheriff's Department launches an investigation into a grave located directly on their treasure site. In Utah, the Dillmans call in a geophysicist to pinpoint underground caves and caverns, leading to one of the largest finds of their family's 56-year hunt.

In Utah, the Dillman family drill into what they believe could be the hidden treasure chamber that their late grandfather predicted. After a close encounter, the Gold Miners in Nevada must find another way into the rest of the underground tunnel system. Meanwhile in New Mexico, after weeks of digging in the Fire Pits with numerous signs of the Conquistadors, the Villescas family makes an underground discovery that could blow their search wide open.

In Utah, the Dillmans must be careful not to trigger an Aztec water trap while digging deep into the cave chamber. In New Mexico, after finding a man-made vault, the Villescas family discovers that there are more secrets buried beneath the Fire Pits. Meanwhile, the Miners in Nevada finally bring in explosives to blow open the mystery waiting for them behind the walls of their mine shaft.
