The Teton Range, centerpiece of the Grand Teton National Park in northwestern Wyoming, belongs to the majestic Rocky Mountains. John Colter, who was part of the Louis and Clark Expedition, is said to have been the first Anglo-American to set eyes on the Tetons, which are lauded for their striking beauty. For the later adventurers who are credited with giving the mountains their suggestive name, the peaks clearly exuded a feminine allure.
Soon after Colter split from the Lewis and Clark Expedition and came across the Teton Range in 1807, the region began attracting French-Canadian fur trappers who sought beaver pelts to make hats. Three of the range's peaks resembled the feminine physique, so the trappers called the trio "les trois tetons," which in French translates to "the three breasts." Eventually, the mountains came to be known as the Grand Tetons, French for "big breasts."
