Two of wolf OR 7's pups peek out from a log on the Rogue River-Siskiyou National Forest, June 2, 2014. The gray wolf, dubbed OR 7, became well known when he traipsed into California in December 2011, making him the first known wild wolf in the state since 1924. He traveled more than any of the seven wolves collared, making him a celebrity and the focus of a documentary being made to track his progress, Wolf OR 7 Expedition.
