“On the Ice,” the Alaska-set thriller by Andrew Okpeaha Mac-Lean, picked up the narrative feature award at the 2011 Woodstock Film Festival, with water-contamination doc “Semper Fi: Always Faithful” nabbing the docu laurel.

“Semper Fi,” which had its world preem at Tribeca earlier this year, also scored the aud kudo for doc, with Emilio Aragon’s Spanish Civil War-set tale “Paper Birds” winning the festgoer vote for top narrative pic.

“On the Ice,” which preemed at Sundance this year, also took home the trophy for cinematography, one of about 10 competitive kudos given out at Woodstock.

Festival’s award ceremony included a tribute to the late filmmaker Gary Winick.

“Ice,” set among Alaska’s Inupiaq people, follows two teen boys who discover a dead body. Pic previously scored a pair of honors at Berlin, including top debut, but, like “Semper Fi,” hasn’t yet been picked up for distribution.

The 12th annual fest closed Saturday with Tony Kaye’s “Detachment.”
