The Mystery of Eric Robinson: A Solo Hiker Who Vanished Without a Trace

In March 2008, Eric Robinson, a 60-year-old Australian retiree and experienced hiker, set out alone on a trail through New Zealand's Southern Alps. He carried a GPS beacon, a tent, extra food, and a waterproof jacket. He had a saying: "There's no such thing as bad weather, just a poor choice of clothing." When torrential rains swept the region and he failed to meet a friend in the resort town of Wanaka, his wife Marilyn received the call she had dreaded. Eric Robinson had disappeared on the Cascade Saddle track, a steep, exposed route known for claiming lives when its grassy slopes become slick with rain. The search that followed would reveal not only the mystery of what happened to one man, but the deeper forces that drive people to push themselves into wild, dangerous places alone.

Turns out, the mountains where Eric disappeared are known for keeping their secrets. Uinta Triangle tells the story of the desperate search for Eric.
