It's not a real desert hike unless you get thirsty. Unless your skin gets punctured by an innocent-looking plant. Unless you have a close encounter with a nervous venomous critter. The desert is alive, and it will defend itself. And we will help. 90 Miles from Needles’ cohosts Chris Clarke and Alicia Pike bring you stories from far out in the American outback: a land unlike any other that is both intense and subtle, that has endured for eons in the harshest conditions imaginable but which could go away in a heartbeat if we act the wrong way. Science, politics, hiking and history, culture and creativity all go into defending the desert. Be forewarned.: We are out to recruit you to the cause.
