Uinta Triangle

Uinta Triangle

Australian trekker Eric Robinson loved to hike. He had a passion for walking in the wilderness, sometimes spending weeks alone in the outdoors. Until one time, he didn’t come home. Eric vanished into a mountain range that has a habit of swallowing people. Uinta Triangle tells the story of the desperate search for Eric Robinson. Host Dave Cawley (journalist and creator of the hit true crime series COLD) follows in Eric’s footsteps. And he joins Eric’s wife, Marilyn Koolstra, in her worldwide hunt for answers about her missing husband. Uinta Triangle is an immersive story of investigation and adventure. It’s also an exploration of how far any of us are willing to go for the people and the places we love.
