In 1834, Osborne Russell joined an expedition from Boston, which proceeded to the Rocky Mountains to capitalize on the lucrative salmon and fur trade. Beginning at the age of twenty, he detailed the life of a trapper in his journal and recorded his adventures through treacherous terrain, encounters with dangerous wildlife, and confrontations with the natives of the Rockies.
Osbourne would remain there—hunting, trapping, and living off the land—for the next nine years. Journal of a Trapper is his remarkable account as he developed into an experienced trapper and a seasoned mountain man of the Rockies.
