Swiss national Enz Ferdinand, 69, became stranded while attempting to descend from Hickman Natural Bridge to the bridge trailhead via an unmarked route. Ferdinand's progress was checked 50 feet above the trailhead after he scrambled through some extremely dangerous/exposed terrain. Park personnel were able climb to Ferdinand's position using a 30-foot extension ladder and traditional climbing techniques. Ferdinand, an avid alps climber, rappelled to the trailhead on belay. The operation took three hours.
