What Is a Bark Scorpion?

When a rafter was stung by a scorpion, she assumed she’d be fine. Within hours she lost her ability to see or speak clearly. It was the beginning of a nightmare that nobody in her group of experienced adventurers saw coming. After all, there aren’t supposed to be deadly scorpions in the United States. But as her condition grew more frightening, they began to believe they had a serious emergency on their hands. In this episode, a collaboration with the Out Alive podcast, we investigate how an unfortunate backcountry incident turned into a medical and scientific mystery.
