Five hikers were killed by a rock slide on a trail in south-central Colorado and another was pulled out with injuries and flown to a hospital, authorities said.
Boulders exceeding 100 tons crashed into a viewing area a half-mile (800 meters) up a popular day hike area, Chaffee County Undersheriff John Spezze said.
The slide left a football-field-sized gash below Mount Princeton, a 14,197-foot (4,327-meter) peak. A female hiker who heard the slide ran down the trail and called for help, Spezze said.
Rescuers found five dead bodies and a 13-year-old girl with a broken leg and other injuries. The girl was flown to a Denver hospital.
There was no immediate identification of the victims or whether they were a single group.
