Five hikers killed in Colorado rockslide

A late-morning rockslide on a Colorado trail killed five hikers and caused a teenage girl to be flown to a hospital with injuries, authorities said Monday.

Police received a call about 11 a.m. (1 p.m. ET) about a rockslide on an easy hiking trail to Agnes Vaille in Pike and San Isabel National Forest, a 2½-hour drive south of Denver. Rescue crews worked at the scene for hours, but early Monday evening the Chaffee County Sheriff's Department told reporters that five of the six hikers were dead.

A 13-year-old girl, identified as Gracie Johnson, was airlifted to Denver Children's Hospital earlier Monday afternoon. She suffered a broken leg, the Denver Post reported.

The ages of the other victims haven't been released. Their bodies won't be recovered until Tuesday at the earliest because the area is unstable, the sheriff's office said.

In May, a rockslide closed part of Interstate 70 in western Colorado when a boulder almost 10 feet wide tumbled across the highway, said Amy Ford of the Colorado Transportation Department.

"Rockfalls, sadly, are something that are common in mountain areas," Ford said, adding that the excessive rain due to the catastrophic flood earlier this month increases the likelihood of rockslides.
