Hundreds of people go missing in US National Parks every year. While many of those cases eventually find resolve, some people, like Joe Halpern, remain missing as the seasons change and the decades pass. Despite the passing of time, loved ones never forget their people who wandered into the woods and were swallowed by the trees - and they’ll do everything it takes to find them.

We love our National Parks and we know you do too but when you're out there, remember to enjoy the view but watch your back.
