The 25-year-old, who has already claimed silver and bronze medals in the discipline and gold in slopestyle at the Winter X Games this year, scored 189.50 points to beat nearest challenger Enni Rukajarvi of Finland by a margin of 24.25.

A double cork 1080 in her final attempt at the jump earned her 100 points and sealed victory. 

"I've known I've got the tricks to win here, but you have to bring them on the day," Gasser, a world silver medallist in slopestyle two years ago in Austrian resort Kreischberg, told Eurosport.

"It's unbelievable; I do not think this jump had been done by a woman before me.

"My season has been so good so far, but the others will certainly work hard in the summer."

Rounding out the podium was Norway’s Silje Norendal, who finished 26.75 points back in third.

Norendal’s compatriot Staale Sandbech won the equivalent men’s event with a score of 188.25 points.

The United States’ Chris Corning finished second with 182.75 points, while another Norwegian, Marcus Kleveland, came third with 177.25.

Action in Sierra Nevada is due to continue tomorrow.
