GRAND CANYON NATIONAL PARK, Ariz. — A 13-year-old North Dakota boy has survived a fall of nearly 100 feet at the North Rim of the Grand Canyon during a family trip. Authorities said it took emergency crews two hours to rescue Wyatt Kauffman after he slipped on a cliff Tuesday and plunged the nearly 100 feet (30 meters) at the Bright Angel Point trail.
