Criner shared a video of the moment to Twitter where concertgoers can be seen running as her sister screamed in pain from the hail striking them. Others sought hiding places under trees and in bushes.

Hail hurts dozens of concertgoers, scraps Louis Tomlinson show at Red Rocks Amphitheater near Denver.

Criner said the sign kept their heads partly covered, but their hands, backs and shoulders were pelted by stinging hail. Criner’s glasses fell from her head and were swept away in a river of hail flowing nearby.

A brief but fierce storm pummeled concertgoers with golf ball-sized hail as they scrambled for cover at the famed Red Rocks Amphitheater near Denver, injuring dozens and forcing the cancellation of the show’s headliner, former One Direction member Louis Tomlinson.

As many as 90 people were treated for injuries from Wednesday night’s storm at the outdoor venue in the foothills of the Rocky Mountains and seven people were taken to a hospital, West Fire Rescue said.

Some were hurt by hail and others had broken bones, bruises and cuts while seeking shelter, but no injuries were life threatening, fire rescue spokesperson Ronda Scholting said.

Sprinkles of hail began falling as Nicole Criner 28, and her sister were making their way to the car to escape the intensifying storm.

Before they could make it, larger hail stones began pelting them, and they grabbed a small plastic sign at the venue’s entrance to cover their heads.
