(AP) — Five hikers were killed by a rock slide on a trail in south-central Colorado on Monday, and another was pulled out with injuries and flown to a hospital, authorities said.

The Chaffee (CHAY’-fee) County Sheriff’s Department confirmed the deaths and said recovery would wait until Tuesday to make sure the area is safe.

The slide occurred at about 11 a.m. on the trail to Agnes Vaille (VAYL) falls in the Pike and San Isabel National Forest, an easy day hike about a 2 1/2 hour drive southwest of Denver.

A 13-year-old girl who survived the slide was flown to a hospital in Denver for treatment. There was no immediate identification of the victims.
