While many Jackson Hole locals flocked to the Tetons for a day of powder skiing on February 15, 2020, Teton County Search & Rescue volunteers loaded up their heavy packs for routine training on Snow King Mountain.


But the training session quickly turned into a life-or-death emergency when longtime TCSAR volunteer Robb Sgroi came down with a rare and severe form of anaphylaxis.


Most people associate anaphylaxis with bee stings, which of course is not possible in Jackson Hole in the middle of February. Anaphylaxis can also be brought on by food allergies that kick someone’s immune response into overdrive and may therefore shut down vital organs. But that’s not what happened here, either.


So how did Sgroi—a tall, lean husband and father—end up itchy, on the ground, and spiraling into unconsciousness? This episode explores the mysterious reasons for his condition, how the team was able to diagnose it in the field, and ultimately save his life.
