Chloe Kim notched arguably the most impressive feat of her young snowboarding career, becoming the first woman to land back-to-back 1080s and scoring a perfect 100 at the U.S. Grand Prix in Park City, Utah, on Saturday.

Kim, 15 and the two-time reigning Winter X Games champion, may have become the second rider to ever score 100 in a top-level halfpipe contest.

When Shaun White scored the first 100 in X Games history in 2012, “it was the first perfect score and perfect run ever seen in a halfpipe contest,” according to the Denver Post. In that run, White reportedly became the first rider to land back-to-back double cork 1260s.

Nobody has scored 100 in an X Games or the Olympics since. The 100-point scoring system was first used at the Olympics in 2014.

Like White, Kim’s perfect run came on a “victory lap,” after she had already clinched the win in an earlier run.

After Kim finished her run, three-time Olympic medalist Kelly Clark raised Kim’s left arm. When the 100-point score came up, Clark receded and allowed Kim to soak in the moment.

Clark, who is 17 years older than Kim, became the first woman to land a 1080 in 2011.

Kim, who was too young for the Sochi 2014 Olympics, is slated to compete in the Youth Olympic Games in Lillehammer, Norway, later this month.
