Grand Teton is the highest mountain within Grand Teton National Park.

The origin of the name of the mountain is controversial. The most common explanation is that "Grand Teton" means "large teat" in French, being named by either French-Canadian or Iroquois members of an expedition led by Donald McKenzie of the Northwest Company.[1] However, other historians disagree, and claim that the mountain was named after the Teton Sioux tribe of Native Americans.

Grand Teton can be scrambled via the Owen-Spalding route but is highly exposed. The route is named after the climbers who made the first ascent: William Owen, Franklin Spaulding, Frank Peterson, John Shive.
