Today we talk about the disappearance of Alfred Beilhartz, one of the most baffling cold cases in the history of the National Park Service.

In July 1938, four-year-old Alfred was on a family vacation in Colorado’s Rocky Mountain National Park. While hiking near a stream with his father, the young boy vanished in a matter of seconds. Despite a massive search effort involving hundreds of volunteers and bloodhounds, not a single trace of Alfred - no clothing, no footprints, and no remains - was ever found.

In this episode, we’re exploring the strange details that have fueled decades of speculation: the "impossible" terrain for a toddler to navigate, the mysterious sighting of a boy on a high ridge known as "Devil's Nest". Was it a tragic accident, a swift abduction, or something that defies conventional explanation? We’re heading into the high country to trace a trail that went cold nearly a century ago.

Watch your step, the mountains have a way of keeping what they find.
