The Ramshorn Dude Ranch Lodge in Grand Teton National Park was built after 1935 by mountaineers Paul Petzoldt, founder of the National Outdoor Leadership School, and Gustav Koven.

The property that became the Ramshorn Ranch was originally established by Ransom Adams at the mouth of Gros Ventre Canyon near Ditch Creek.

By 1921 the property was acquired by Jack and Dollye Woodsman, who established the Flying V dude ranch, featuring a large central lodge.

A variety of owners and partners ensued until 1956, when the ranch was sold to the National Park Service.

[2][3][4] The lodge is now the main building of the Kelly Campus of the Teton Science School, and retains its rustic character.
