Bernhard Rietmann had a great sense of wanderlust. His drive for adventure landed him in Jackson Hole in the 1960s. Back when tourists only came in summer and innkeepers routinely hung up a gone fishing sign after Labor Day.

After decades of exploring the valley, Rietmann knew the Granite Creek Drainage well. He often went hunting there solo. On Sept. 23, 2015, carrying a sandwich, a water bottle and a rifle, the 84-year-old went looking for deer. When he didn't return, a massive effort mobilized to find him.

In this episode, Rietmann's son, Max, and longtime TCSAR volunteer Alex Norton give an inside look at how the search panned out.
