Mystery at Blind Frog Ranch
Discovery Documentary
What it is
There are some places on earth where the land just seems different, and Blind Frog Ranch in eastern Utah is one of those places. Locals say the land is cursed. That it's trying to hold on to something. From Aztec treasure to caverns of gold and silver to lost Mormon mines, legends surround Duane Ollinger's 160-acre ranch in Utah's Uintah Basin. But Duane isn't concerned with the lore. After discovering a system of seven underground caves that run through his property, he is singularly focused on finding what's hidden in them - no matter what the cost.
