From Macleans.ca in Canada:
Years ago, on a dark December morning, Ron Doctor was driving alone through the snowy hinterlands of the Northwest Territories when he spotted something odd in the thick, fresh snow. He couldn’t get a good look, so he drove home and returned to the scene during his precious four-hour window of subarctic daylight. The second visit confirmed his suspicions: these were giant wolf tracks, 7½ inches long.
“Holy smoke,” the veteran wildlife officer thought to himself. “This is unreal.” He’d never seen a wolf track that big.
