It was Outtrim's second victory of the weekend after she won the moguls title on Friday, while Wilson finished in second place on Friday.
"It feels amazing," Outtrim said of her two titles. "I don't really know what I expected this week. There weren't that many [U.S. Ski] Team members here, so I was really hoping that me and the few teammates here could sweep the podium. It's a little unexpected I suppose. It was a lot of duels skiing today. We had to duel from a round of 32, which is unusual because in World Cup we only duel from 16. I was just happy to make it to the finals and get Sophia [Schwartz]."
On the men's side, Nick Hanscom (Park City) skied into second in the big final, while Joe Discoe (Telluride, Colo.) took the third spot with Jay Panther (Park City) fourth. Dylan Walczyk (Rochester, N.Y.) finished fifth.
U.S. Ski Team rookie Sophia Schwartz (Steamboat Springs, Colo.) finished second in the women's big final, her second silver medal of the weekend. Elizabeth O'Connell (Winter Park, Colo.) finished the day in third with Lane Stoltzner (Steamboat Springs, Colo.) fourth. Stoltzner also notched a third place on Friday.
Sunday's event wrapped up the U.S. Freestyle Championships and capped another incredible season for U.S. Freestyle Ski Team.
