Duane Ollinger, the businessman and reality television personality best known for starring on Discovery Channel’s Mystery at Blind Frog Ranch, has died at the age of 68.
According to reports confirmed by his family, Ollinger passed away Tuesday at a hospital in Texas following a battle with amyotrophic lateral sclerosis, commonly known as ALS.
Became Popular Through Treasure-Hunting Series
Ollinger gained a loyal fanbase after Mystery at Blind Frog Ranch premiered in 2021 on Discovery Channel.
The show followed Ollinger, his son Chad and a team of investigators as they searched for what they believed could be hidden treasure buried beneath his Utah property near the Uintah Mountains.
The series mixed treasure hunting, underground cave exploration and paranormal mystery elements that quickly attracted viewers.
From Oil Business to Reality Television
Before becoming a television personality, Ollinger built his career in the oil industry and reportedly earned significant success as a high-risk oil contractor based in Texas.
After selling his business, he invested heavily into the Blind Frog Ranch property and became convinced valuable treasure and mysterious underground tunnels existed beneath the land.
That belief ultimately became the foundation for the Discovery Channel series.
