This photo was taken on Jeff Clow's 2nd Annual "Dirt Cheap Photo Tour" of the Grand Teton National Park in Wyoming. About a half mile North of the quaint city of Kelly grazed a herd of Bison in the late afternoon. Although they seemed unaffected by our presence, we photographers were "on edge" the entire time as these massive animals strolled by at a very leisurely pace.
The American bison (Bison bison) is a North American species of bison, also commonly known as the American buffalo. Some consider the term "buffalo" somewhat of a misnomer for this animal, as it is only distantly related to either of the two "true buffalo," the Asian water buffalo and the African buffalo. However, "bison" is a Greek word meaning ox-like animal, while "buffalo" originated with the French fur trappers who called these massive beasts bœufs, meaning ox or bullock – so both names, "bison" and "buffalo," have a similar meaning. In reference to this animal, the term "buffalo," which dates to 1635, has a much longer history than the term "bison," which was first recorded in 1774. The American bison is more closely related to the wisent or European bison.
