"There's a good chance," he said. "One thing they do regularly is surprise us. [In 1998, a] wolf swam down the Snake River, shook itself dry and came over to Oregon, and three years later we had one on the west side of the state. The trick is that there is a gap in good wolf habitat between where they currently live in Oregon and the Cascades. So it's going to take a few brave, wandering wolves from elsewhere to cross and then find each other."
