Their is controversy over who reached the peak of the Grand Teton first. Both Nathaniel Langford and James Stevenson claim to have reached the top on the same day.
The mountains that now constitute Grand Teton NP were first seen by humans about 12,000 years. The exact time and person have been lost to prehistory.
Grand Teton, at 13,775 feet is the high point of the Teton Range, and the second highest peak in the U.S. state of Wyoming. The mountain is entirely within the Snake River drainage basin, which it feeds by several local creeks and glaciers. Grand Teton's name was first recorded as Mount Hayden by the Washburn-Langford-Doane Expedition of 1870. But 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. The origin of the current name is a bit controversial. The most common explanation is that "Grand Teton" means "large tit" 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.
