She stood up with blood pouring from her nose as a medical team rushed to her side.
The teenager had been a promising entrant in the finals, and has been spruiked as a younger Torah Bright, who is considered one of the country’s best snowboarders.

Her mother told the Daily Telegraph the fall would not have upset her daughter, who had only dreamed of making the finals at the PyeongChang Games.
‘What a dream this is, first Olympics and her goal was just to make the final,’ she said.
‘She has ticked that box [and] everything from here is a bonus. Absolutely. Making it to the finals we couldn’t be happier.’
The woman revealed Emily found competition ‘more relaxing’ than a practice session, and ‘just loves’ competing.
