Originally attempted to summit via Devil's Backbone but was turned around at Baldy Notch. Second attempt via Register Ridge loop with a descent on Mount Baldy trail. Missed the trailhead up to Register Ridge and went to summit via the Mount Baldy trail. Mistakenly thought the elevation profile was easier on Register Ridge trail. Realized Cory Hoo couldn't get down with the equipment he had. We had to call emergency services. Helicopter couldn't hoist due to wind. Ground team retrieved us and we went down Register Ridge with better gear.
