Grand Teton National Park
The Tetons were known variously as "The Pilot Knobs" and "The Three Paps." The word Tetons is actually a French word meaning "breasts." Iroquois or French-Canadian trappers from the Pacific Northwest may have been responsible for the name Les Trois Tetons meaning "the three breasts."
By the 1820s, the mountains were commonly known as the Three Tetons. The Snake Indians, or Shoshone, called them "hoary-headed Fathers" and "Teewinot" which translates to many pinnacles.
