What better way to celebrate the wonders of nature than by getting all glammed up and hitting one of the city's wildest clubs? So thought the Yellowstone Forever Young Patrons, who last night held a rager for a cause. The official nonprofit partner of Yellowstone National Park, Yellowstone Forever supports the preservation of the American gem, engaging visitors and future stewards for generations to come.

Co-chairs Arielle Patrick, Jackie Rooney, and Alice Ryan joined a lively crowd of well-heeled revelers at LAVO for the annual benefit, where guests sipped Ilegal Mezcal, Archer Roose Wine, and Stella Artois while browsing the silent auction and getting down on the dance floor. The bash went on 'til 11, but the evening certainly didn't end. After-hours, the crowd headed downtown for a post-party at Avenue. 'Twas a Thirsty Thursday (with honorable intentions) indeed.
