Alaska's Wolf Man: The 1915-55 Wilderness Adventures of Frank Glaser by Jim Rearden

Between 1915 and 1955 adventure-seeking Frank Glaser, a latter-day Far North Mountain Man, trekked across wilderness Alaska on foot, by wolf-dog team, and eventually, by airplane. In his career he was a market hunter, trapper, roadhouse owner, professional dog team musher, and federal predator agent. A naturalist at heart, he learned from personal observation the life secrets of moose, caribou, foxes, wolverines, mountain sheep, grizzly bears, and wolves—especially wolves.
