They showed stills on the Today show and it looked kinda bad. From the stills she looked like she started up about 30 or 35 feet on a man-made slide about 5 or 6 feet wide covered with fake snow. She went down the hill and on the first landing she lost it and slid right off the thing about 20-25 feet in the air. She's a snowboarder so she has to be tough but she landed on freaking concrete so it definately had to hurt. At least it wasn't a pointy rock.
She landed on her back and looks to be okay.
