Jill Kinmont Boothe, who appeared headed for Olympic glory but who was paralyzed in a skiing accident in 1955, died Thursday, the Los Angeles Times reported. She was 75.

Boothe was the subject of the 1975 movie “The Other Side of the Mountain” and the 1978 sequel “The Other Side of the Mountain Part 2.”

Three days before she was to appear on the cover of Sports Illustrated, she was left a quadriplegic at the age of 18 when she crashed during a race in Alta, Utah. She sustained a broken neck and several spinal cord damage.

She had become the U.S. women’s slalom champion in January 1955.

Boothe died in a Carson City hospital, but cause of death has not been announced, the Times said.

After the accident, Boothe earned a teaching credential at the University of Washington and became a successful teacher.
