White last appeared on the World Cup tour in New Zealand in August 2009, triumphing the halfpipe competition on that occasion to extend his unbeaten streak to three.
Since then White has doubled his Olympic gold-medal tally with a second successive halfpipe title at Vancouver 2010 and claimed four straight superpipe crowns at the Winter X Games.
The last of those came in Aspen just last weekend, making it six in a row in the superpipe for the 26-year-old, who made it four in a row on the World Cup circuit in Park City.
He led home an American one-two-three, claiming victory with a second run score of 97.25 after a fall on his first outing meant he was only awarded 59.50 points.
Scott Lago took second with 94.50 and Luke Mitrani third with 91.75 while there were American's in fourth and fifth in the shape of Gregory Bretz with 89.00 and Louie Vito with 87.25.
White's surprise entry in Park City was in order to garner qualification points towards the Winter Olympics in Sochi in little over a year's time while his arrival also coincided with a sterling performance from Brit Ben Kilner.
The Scottish snowboarded finished a season-best tenth after scoring 51.00 in Utah to claim 260 World Cup points while Mitrani leads the overall standings after three of five events ahead of Lago with 1400 in total.
In the women's halfpipe competition China's Jiayu Liu prevented an American victory as she edged out Arielle Gold in the final, scoring 82.00 to the home snowboarder's effort of 80.25.
However America were still dominant on the podium as Kaitlyn Farrington took third with 73.25 while World Cup leader Kelly Clark fell twice trying to land her first trick and finished sixth.
Clark, who won the opening event in Cardrona and was second last time out on Copper Mountain, still leads the overall halfpipe World Cup standings with a 720-point cushion over Gold in second.
