<P> Grand Teton, at 13,775 feet (4,199 m), is the highest point of the Teton Range, and the second highest peak in the U.S. state of Wyoming after Gannett Peak . The mountain is entirely within the Snake River drainage basin, which it feeds by several local creeks and glaciers . The Teton Range is a subrange of the Rocky Mountains, which extend from southern Alaska to northern New Mexico . </P> <P> Grand Teton's name was first recorded as Mount Hayden by the Washburn - Langford - Doane Expedition of 1870 . However, the name "the Grand Teton" had early currency . The Edition of April, 1901 of the USGS 1: 125,000 quadrangle map of the area shows "Grand Teton" as the name of the peak . A United States National Park named "Grand Teton National Park" was established by law in 1929 . By 1931, the name Grand Teton Peak was in such common usage that it was recognized by the USGS Board on Geographic Names . Another shift in usage led the Board to shorten the name on maps to Grand Teton in 1970 . </P> <P> The origin of the name is disputed . The most common explanation is that "Grand Teton" means "large teat" or "large nipple" in French, named by either French - Canadian or Iroquois members of an expedition led by Donald McKenzie of the North West Company . However, other historians disagree, and claim that the mountain was named after the Teton Sioux tribe of Native Americans . </P> <P> There is a disagreement over who first climbed Grand Teton . Nathaniel P. Langford and James Stevenson claimed to have reached the summit on July 29, 1872 . However, some believe their description and sketches match the summit of The Enclosure, a side peak of Grand Teton . The Enclosure is named after a man - made palisade of rocks on its summit, probably constructed by Native Americans . Mountaineer and author Fred Beckey believes that the two climbed the Enclosure because their description matches it, because their description does not accurately describe the true summit, because their account does not mention the formidable difficulties found just above the Upper Saddle, and finally, because it was traditional with members of the Hayden Geological Survey of 1871 to build a cairn in such a place, but no such cairn was found when William O. Owen reached the summit in 1898 . In all likelihood, The Enclosure was first climbed by Native Americans as suggested by Langford in 1873 . Supporters of Owen included The Wyoming Legislature and Paul Petzoldt, former pioneer American climber . Ironically among Langford's supporters was Franklin Spalding, who led the ascent to the summit and tossed the rope that allowed Owen and the others to follow . </P>
