France's Pierre Vaultier won his second consecutive gold medal in the men's snowboard cross, outdueling silver medalist Jarryd Hughes of Australia and Spain's Regino Hernandez, who won the bronze.
She finished just behind China's Kong Fanying, who was 55th with a combined time of 2:49.88.
By now, Mikaela Shiffrin was supposed to have completed Olympic races in her two best disciplines: slalom and giant slalom.
It's so special in how it has been building this year.
In those Games, Shiffrin, then 18, became the youngest skier to win a gold medal in the slalom.
"Today I was trying really hard but I also was feeling the hill, I was feeling the mountain and I was feeling my skis", she said. The 22-year-old American standout trailed by 0.20 seconds heading into the last run, but made up ground in no time by powering through ruts that had developed on the course.
During the first run, Shriffin wasn't the only competitor attracting attention at the Yongpyong Alpine Center.More news: Alvaro Morata makes vow to Chelsea FC fans ahead of Barcelona clash

Kelli Stack #16 of the United States handles the puck against Laura Fortino #8 of Canada during the Ice Hockey Women's Gold Medal Game on day 13 of the Sochi 2014 Winter Olympics at Bolshoy Ice Dome on February 20, 2014 in Sochi, Russia.
The 31-year-old Anderson admitted conditions were tough, but said she used her "lion power" to pull off a gold medal-winning performance. She will compete for five medals during the competition in the women's super-g, slalom, giant slalom, downhill and combined.
After finishing, Shiffrin put her right glove on her chest, mouth agape. Back then, the notion that Shiffrin would chase medals in five Olympic events seemed more plausible because the races were evenly spaced across 12 days, not wedged into nine action-packed days. "But we're in good shape".
Her mother said the nervousness was due to challenges in finding adequate training time prior to the season and to overcome her anxiety she began working with a sports psychologist.
"I don't think it gets any easier, but I think she can take a deep breath and say, 'The pressure's off a little bit".
Also keep an eye out for Faye Gulini, an experienced snowboarder who is competing in her third Winter Olympics. It's the Women's ice hockey match featuring the USA against Canada, and both countries have alternated between themselves in getting the gold since 1998, except for that one time in the 2006 Winter Games. Her last giant slalom race was January 27 in Lenzerheide, Switzerland, where she finished a disappointing seventh.
It's an ambitious goal that will likely mean she's competing every day until closing ceremony, but if she succeeds, she'll have a shot at Olympic history. "I had a lot of fun racing in front of these awesome people", said Ng. The refined surface came with it a confidence Stiegler hadn't felt through much of her two weeks thus far in PyeongChang.
