The Yukon Trail: A Tale of the North (filmed as The Grip of the Yukon in 1928) is an adventure yarn from the prodigious output of William MacLeod Raine, who averaged nearly two western novels a year for some 46 years. Twenty of his novels have been filmed. Though Raine was prolific, he was a slow, careful, conscientious worker, intent on accurate detail, and considered himself a craftsman rather than an artist.
