Jones books place in final
British snowboarder Jenny Jones moved into the final of the Winter Olympics slopestyle event, but compatriot Aimee Fuller missed out.
Jones' first score of 82.25 was enough to see her seal a top-four finish in the semi-final that was needed to advance to Sunday afternoon's showpiece event.
She then bettered her first score by a point to finish third and raise hopes of Team GB earning their first medal on day two in Sochi.
Fuller was unable to join her, however, after twice being unable to land a double backflip in her runs.
Less than a day on from Jamie Nicholls and Billy Morgan earning top-10 finishes in Saturday's men's final, Jones will now be aiming to continue the feelgood factor over snowboarding in Britain.
In Thursday's qualifiers, she became the first woman to compete in the Olympic snowboard slopestyle event, which is making its debut in Sochi, and finished fifth, requiring her to compete in the semi-final.
But today, she was the last out of the gate and knew what was required of her before setting off.
She benefited from several people - including Fuller - failing to land their jumps, and although she initially struggled on the rail part of the Rosa Khutor Extreme Park course, she completed three excellent jumps to move into third after the first run.
Qualification was already secure by the time of her second attempt, although she did slightly improve to take her place alongside Sarka Pancochova (90.50) of the Czech Republic, Swiss Sina Candrian (84.25) and Norway's Silje Norendal in the final.
"I'm just chuffed," she said.
"It was a bit nerve-wracking having to drop last and then when I realised I'd done it, it was a good feeling."
She will be the second competitor out of the gate in the 12-person final, which gets under way at 1315 local time (0915GMT).
Fuller twice failed to land properly after trying a double backflip, with her first attempt a particularly nasty-looking fall.
But the 22-year-old from Nothern Ireland admitted she was determined not to hold back and has no regrets.
"I laid all my cards down on the table, went for it, didn't quite work out today but I thought I might as well go big or go home," she said.
"After all it's the Olympics, the biggest contest on earth, so I'm pleased I went for it really.
"I'm going to walk away happy and have enjoyed my Olympic experience so far."
