From MPR News:
In the spring of 2017, University of Minnesota graduate researcher Tom Gable had a rare, surreal and as it turns out, fortuitous encounter with a wolf while he was tromping through the thick, swampy woods of far northern Minnesota.
He knew a wolf that researchers had outfit with a GPS tracking collar had been spending time in the area. As he approached, he spotted it splashing in a creek, only 30 feet away. So he quickly hid behind some shrubs, pulled out his iPhone and videoed the scene.
