Spencer O'Brien takes a tumble. She's well out of it. Only five riders still to go and Great Britain's Jenny Jones is in the silver medal position.
Away from the slopestyle for a moment, the men's 30km skiathlon has just started, with Callum Smith making his Olympic debut for Great Britain. And you can watch it on the BBC Sport website.
GB Slopestyler Aimee Fuller on BBC TV: "That is a well placed score from Enni Rukajarvi and a well deserved placing."
Finland's Enni Rukajarvi nails a 720 and punches the air after landing her final jump. And the judges are very impressed - she scores 92.50 to knock Jones down into second place.
Ow! Sarka Pancochova of the Czech Republic loses control off the first jump and lands horribly, bouncing off her board and onto her back and head. After lying winded for a minute or so, she is helped to her feet and manages a smile before cruising down to the bottom of the course. Her helmet has a huge crack down the middle. A sobering moment amidst the euphoria of Jenny Jones.

Oh my word, Jenny Jones leads the slopestyle. Are Team GB going to win a first-ever Winter Olympic medal on snow?
Sina Candrian's effort is much more daring than Jones' but not quite as clean. The judges take an age to decide that .... Candrian's effort is an 87 and only good enough for second. Jones retains top spot with nine riders still to go.

"Jenny Jones cannot believe it. We have a lot of riders still to come, let's be composed here."
James Maher, external: Beautiful run - Jenny Jones absolutely stomped it!
Jools Murray, external: I love that the women are riding the same jumps as the men!
Softlad, external: My four-year-old daughter is jumping off the sofa, loving the girls Jenny Jones and Aimee Fuller on slopestyle.
Wow! wow! She's in first place with an 87.25. Aimee Fuller is screaming. This is amazing stuff. I repeat, Jenny Jones is in first place.
"Solid, solid" screams Aimee Fuller as Jenny Jones slides down the rails and nails her jumps in a clean run. Here comes the score ...

Right Jenny Jones. Now or never!
I hope you are enjoying this as much as we are with your Sunday morning pastries. The sight of these women leaping 50 feet in the air against a backdrop of snow-capped mountains is simply stunning. I have a sneaky feeling that slopestyle is here to stay.
Gasser recovers her composure, but it's a scrappy effort and she posts a 49.00 for ninth place. Jenny Jones is in fifth after the first run so she must improve to have a chance of a medal. Seconds out for the second round.
Comedy capers in the snow-boarding. Anna Gasser sets off too early, then stops and takes her board off before trying to climb back up to the starting hut. Her coach tries to help her and slips down the slope. He gets back up then Gasser tries to clamber back up on all fours, only to slip and slide back to the bottom. Hugely embarrassing for the Austrian but hilarious for the rest of us.
Dan Maskell would be turning in his grave. Aimee Fuller has just criticised a boarder for "butt-checking" after a jump!
Favourite Jamie Anderson scuffs the final ramp but goes into second place with 80.75.
Team GB snowboarder Jamie Nicholls on team-mate Jenny Jones' first-round score of 73.00, which currently has her fourth in the snowboard slopestyle final at the Extreme Park in Rosa Khutor.
"Jenny is a solid snowboarder - great on the rails and with the jumps," he told BBC Sport.
"I can see her delivering her best today but she needs to step it up in the second round - she needs [a score of] at least high 80's I think."
GB Slopestyler Aimee Fuller on BBC TV: "Torah Bright is out here and she is just going for it. That is progression at its finest. Aussies going wild for their home girl."
Australia's Torah Bright takes the breath away as she sails up into the clouds off one of the huge ramps. She lands an unprecedented switch 900 but she pays the price for her hand dragging in the snow and can only post a score of 64.75.
After eight of the 12 riders in the slopestyle, Britain's Jenny Jones is in fourth place. Switzerland's Elena Koenz makes me wince with an ugly fall, but she's fine, with only her pride bruised.
