Black bears in the Smokies are black in color, but in other parts of the country they may be brown or cinnamon. They may be six feet in length and up to three feet high at the shoulder. During the summer months, a typical adult male bear weighs approximately 250 pounds while adult females are generally smaller and weigh slightly over 100 pounds. However, bears may double their weight by the fall. Bears over 600 pounds have been documented in the park. Bears can live 12-15 years or more, however bears which have had access to human foods and garbage have a life expectancy of only half that time.
