Kearney couldn't have asked for a better venue as she made her 100th World Cup outing, taking to the slope in her homeland.
And she ensured it was a double celebration as she claimed victory, meaning that in 57 per cent of the moguls events she's ever entered, she has reached the podium, winning 38 per cent of the time.
And win number 38 of her remarkable career came as she held off Canadian Chloe Dufour-Lapointe and her younger sister Justine, the siblings settling for second and third respectively.
Kearney sits atop the World Cup moguls standings on 280 points, with Justine Dufour-Lapointe 40 points further back in second and Chloe Dufour-Lapointe third on 185.
In the men's event it was a Canadian clean sweep as Mikael Kingsbury picked up the win and was joined on the podium by compatriots Alex Bilodeau and Marc-Antoine Gagnon in second and third respectively – the latter celebrating his first-ever World Cup podium finish.
Kingsbury leads the overall World Cup standings on 300 points, with Bilodeau 60 behind in second, with American Patrick Deneen in third on 140 after he finished sixth at Deer Valley.
