A 10-year-old Alberta girl who went on a ski trip with her school has died after she lost control of her skis and struck a wooden pole.

The student was wearing a helmet at the time but still suffered serious head injuries in the crash, the RCMP said.

The incident happened Tuesday at the Castle Mountain resort in Pincher Creek, Alta. Officials have not released the child’s identity, but have said she was a Grade 6 student from nearby Pincher Creek’s Canyon Elementary School, which provided chaperones on the trip.

“We have school groups almost every day," resort spokesman Jason Crawford told the Canadian Press Wednesday. The girl, who had skied at the resort before, took a mandatory skiing lesson with classmates in the morning before heading down a beginners’ hill alone. "Once they're through their lesson, they're able to ski on the hill,” said Crawford, confirming that the resort is investigating the incident.

According to RCMP, two other students witnessed the girl go off the run and hit the pole along a fence lining an out-of-bounds section. First aid was administered to the girl by staff from the ski resort before she was rushed to Alberta’s Children’s Hospital in Calgary, where she was later pronounced dead. Because of strong winds and snow, she could not be air-lifted to hospital, said RCMP Sgt. Mark Harrison.

"The Canyon School Community is devastated by this loss," said Canyon School principal Paul Pichurski of the The Livingstone Range School Division, which is providing counselling to students at the school. "We send our heartfelt condolences to the family."
