Two experienced female skiers suffered fatal injuries this past week. Both apparently lost control and collided into a tree.

Officials report that a nine-year old Calgarian, a member of the Mount Allen ski team, crashed into a tree at Nakiska Ski Resort. On Sunday, the girl was found unconscious and unresponsive by other skiers around 1 p.m. She was treated at the resort, and then rushed to Alberta Children’s Hospital.

The girl, whose name has not been released, died in hospital later Sunday.

It’s not known exactly how it happened, but Alberta Alpine said the young girl was skiing with her team, which is part of a weekend program staffed by professionally trained coaches and instructors. It’s believed the girl’s helmet came off in the collision.

A second death has been reported by officials, a snowboarder has died following an accident at the Jackson Hole Mountain Resort.

The Jackson Hole News and Guide reports that the woman, who has not yet been identified, died Monday after ski patrol staff received a report of an accident on one of the trails.

The woman was found in the trees below the Togwotee Pass traverse. Patrollers attempted to revive the victim. She was taken to a hospital and later pronounced dead.

These accidents are sad reminders that early season conditions may be less than ideal and extra caution should be employed to remain in control.
