The wolf pup had downy fur and a chubby little belly. But as it bolted from the den, it already showed signs of an adult wolf’s fleetness. Lacy Robinson was close behind, but not quick enough. After a scramble through the brush, the pup disappeared into the dense forest of the North Fork of the Coeur d’Alene River drainage. Robinson returned to the den, where seven wolf pups remained to be outfitted with tiny radio collars. “Maybe if it was an equal footrace,” she said with a rueful sigh, noting that the wolf pup had the advantage of ducking under fallen logs.
