English mountaineer William Baillie-Grohman wrote in an 1882 memoir that “there are few spots in the Western mountain lands about which there hangs so much frontier romance,” and attributed this to “the quite exceptional natural beauty of the spot.” The naming of the mountains is attributed to early 19th-century French-speaking trappers—les trois tétons (the three teats). A number of stone enclosures on some of the peaks, including on the upper slopes of Grand Teton (known simply as The Enclosure) are thought to have been used by Shoshone during vision quests.
