Host Boyd Matson guides Wild Chronicles up a cliff face in Seneca Rocks, West Virginia, to experience a climber TMs rite of passage. On a multiday climb, sleeping on a rock face is often a necessity, so climbers rely on a porta-ledgea precariously perched home away from home. But 200 feet above the ground, setting the porta-ledge and climbing in is no easy task. Whatever you do, don TMt look down.
