Mystery at Blind Frog Ranch, Underground Tsunami

Duane and Chad Ollinger return to Blind Frog Ranch, armed with cutting-edge tech, to unearth $3 billion in hidden treasure. Shocking new information on the underground tunnel emerges. Claim jumpers invade the property, threatening to derail everything.

Searching for the hidden entrance to the cave system, the team uncovers an ancient vent shaft above the Energy Zone. But an explosion triggers an underground tsunami that threatens to flood the cave system.

When an underground tsunami floods the cavern system, Duane and his team attempt to breach it from higher ground -- discovering evidence of Aztec artefacts, and a crucial clue to the Lost Rhodes mine.

After uncovering a bar of gold at the Bead Site, Chad, and James set out to research where it might have come from. With trespassers still threatening the ranch, their discovery sets them on the path of the fabled Lost Rhodes Mine.

In a dangerous manoeuvre on the trail of the Lost Rhodes Mine, Chad, and Ryan try to rappel down a 250-foot cliff to access the Mormon Eye cave. James suffers a high-altitude health scare. Duane uncovers more poacher sites on the ranch; he intervenes.

Now that the floodwaters have receded at the Energy Zone, the team prepares to resume drilling into the cavern system. Duane takes a stand to remove the poachers from his property. Charlie unearths a deer carcass with unusual bite marks on it.

While drilling into the cavern system to find the Aztec gold, the team strikes an impenetrable object deep below ground. Tests of the site reveal the truth about the Energy Zone, and what lies beneath Blind Frog Ranch.

After hitting a meteorite deep underground while trying to drill into the cavern system, the team searches for an alternate route. While scouring the area, Chad discovers a clue that finally leads to a breakthrough.
