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 a federal predator control agent. A naturalist at heart, he learned from personal observation life secrets of moose, caribou, foxes, wolverine, Dall sheep, grizzly bears, and wolves—especially wolves. A superb shot, self-sufficient, and wilderness wise, Glaser not only survived, but prospered in the far lonely places. Almost always alone, he survived many encounters with charging grizzly bears, some of which he had to shoot to keep from being mauled. He knew how to cope with 50 and 60 below zero temperatures, and more than once he plunged through the ice in extreme cold and survived only because of his woods know-how.
