Silje Norendal scored her second X Games slopestyle gold medal in as many years earlier today, with a victory over the ever-dominant Jamie Anderson.

The women's slopestyle snowboarding that we watched today was some of the strongest female riding we've seen to date, with Spencer O'Brien putting down the back 9, and cab 900 attempts from Jamie Anderson.

Silje Norendal was back to defend her gold medal from last year, and although she left it until her final run, defend it she did, pipping Anderson to the top spot with a run that included a frontside 720 off the toes, big backside 540 and cab 720.

Kiwi ripper Christy Prior rouned out the podium in third, a stellar showing for her first ever X games appearance.

Women's Winter X Games 2015 Slopestyle Results:

1st: Silje Norendal (NOR)

2nd: Jamie Anderson (USA)

3rd: Christy Prior (NZL)

Christy Prior has been killing it for years now, although remarkably, this was her debut performance at X Games and was enough for bronze medal.

While her rail game wasn't quite as on-point today as we've come to expect from her, with relatively simple (by her standards anyway) switch boardslide, gap front board and 50-50 backside 180 off, Christy's kicker riding was solid. In her third and final run she stomped cab underflip, backside 720 and front 5 off the toes, which saw her jump from 8th to a spot on the podium.

4-times Winter X Games slopstyle gold medallist and defending Olympic gold medallist Jamie Anderson kept it safe in her second run, with a layback wallride, gap to lipslide, backside tailpress, frontside 720, backside 540 and cab 720 - posting a score that stuck in the top spot for the duration of the contest.

In Jamie's third run she took a gamble and went for a cab 900 on her final hit, but by not stomping it clean, she left the door open for Silje.

Silje Norendal made it count when it mattered most, stomping a clean third and final fun to pip Jamie Anderson's second run score.

Her run included a front 180 cab 180 combo on the wallride, bluntside 270, 50-50, frontside 720 off the toes, backside 540 and cab 720 - a very similar run to her gold medal winning run in 2014.

While Silje's winning run may not have been a major step up from her run in last year's competition, there was definite progression elsewhere in the women's comp, with Spencer O'Brien landing a sick backside 900 as part of her slope run. Check it out on the next page.

Spencer O'Brien made history today with the first backside 900 ever landed in a women's X Games slopestyle finals in 2015. The history of that trick is more convoluted than the organisers were making out - a good read on it is here.

Congrats Spenny!
