盲蛙牧场藏宝之谜

Duane and Chad Ollinger return to Blind Frog Ranch, armed with 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 artifacts 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 maneuver 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.
