In a huge event with 63 competitors, the 27-year-old qualified fourth in his qualification heat with a top score of 84.66 to have a run in the top-16 final.
He unfortunately couldn’t complete his full run in the final, finishing in 16th place, which is a season’s best for Australia’s top slopestyle skier.
Canada’s Teal Harle won gold with a best run of 94.20, ahead of Swiss skier Andri Ragettli and fellow Canadian Evan McEachran.
Having overcome injury and illness that impacted his opening two World Cups, Henshaw went into the event feeling more confident than he had all season after he put down a solid run at last weekend’s Snowmass World Cup, where he finished 34th with a top score of 79.33.
The Sydney-sider made his Olympic debut at Sochi 2014 when the sport of Ski Slopestyle appeared in the Olympic program for the first time. He will be looking to improve on his 8th place finish from Sochi if he is selected in his second Winter Olympic Games Team for PyeongChang 2018.
His fellow Australian teammates Nic Stevens finished 41st at Mammoth with a top qualification score of 50.33.
