The 1913 Moulton Barn in Grand Teton National Park in Wyoming. The park is named for Grand Teton, the tallest mountain in the Teton Range of the Northern Rocky Mountains. The naming, attributed to early 19th-century French-speaking trappers—"les trois tétons" (the three teats)—was later anglicized and shortened to Tetons. Thomas Alma Moulton and his sons built the barn. The property with the barn was later one of the last parcels sold to the National Park Service by the Moulton family. Often photographed (some say it is the most-photographed barn in America), the barn with the Teton Range in the background has become a symbol of the area called Jackson Hole.
