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

There is a controversy over who made the first ascent of Grand Teton.
Nathaniel Langford and
James Stevenson claimed to reach the summit on July 29, 1872. However, their description and sketches match the summit of
The Enclosure: side peak of Grand Teton. The Enclosure is named after a man-made palisade of rocks on its summit, probably constructed by
Native Americans.
When William O. Owen climbed the true summit, he found no trace of
prior human passage. Therefore, The Enclosure was probably first
climbed by Native Americans, and the true summit was first climbed by
William Owen.
