The third book in Boone and Crockett Club's series of digitally remastered classics. Join Charles Sheldon in this wonderful book recording two years of field experiences while engaged in studying wild sheep of Yukon Territory from 1904 to 1905. This detailed account is strictly from the point of view of a hunter interested in natural history. Sheldon travelled by steamboat, canoe, pack horses and on foot as he was accompanied by other well known explorers of his generation such as Frederick C. Selous, William H. Osgood, and Carl Rungius. Along with mountain sheep, Sheldon also encounters moose, grizzly bears, and caribou. The Wilderness of the Upper Yukon is profusely illustrated with nearly 100 photographs and paintings from the trip including four detailed maps of his travels.
