A mountain rockfall tumbled onto a family truck on the picturesque Going-to-the-Sun Road in Glacier National Park on Aug. 13, killing a 14-year-old girl and leaving four others injured.
Officials at the park in Montana estimated that the rocks, which ranged from fist-sized to a foot in diameter, rained down on the truck, according to local reports, as it approached a tunnel on the popular road that winds through the mountainside.
An air ambulance was called in, but could not transport the girl due to her unstable condition, the park said.
She died in an ambulance on her way to the hospital.
The death of the teenager is the first from a rockfall on the immensely popular road since 1996, when a vehicle was hit west of Logan Pass.
A picture obtained by NBC shows rocks and debris scattered across the road in front of a tunnel.
The park said that the rockfall amounted to about enough to fill a flatbed truck.
Going-to-the Sun Road is closed during winter, but during the summer becomes a highly popular drive for tourists who want to take in the dramatic mountain scenery of the park.
Founded in 1910, and drawing in almost 3 million visitors a year Glacier National Park squeaks into the top 10 list of the most popular of America’s 60 designated national parks.
With tourist season in full swing in summer, the number of accidents at national parks rises.
