The Ramshorn Dude Ranch Lodge, now the main building of the Teton Science School, is located in the southeastern corner of Grand Teton National Park. The Teton Science School campus contains the Lodge, over fifteen residences and small cabins, an ice house, a historic barn, and the imposing Hunter Hereford residence, moved from the Hunter Hereford Ranch and converted to a dining room in 1990. While the entire property retained insufficient integrity of setting and association for listing in the National Register of Historic Places as a historic district, the Ramshorn Lodge retains remarkable integrity of design, workmanship, and materials, and is significant for its characteristics of dude ranch rustic architecture.

In 1935, mountaineer and climbing concessioner Paul Petzoldt (who would later found the National Outdoor Leadership School) purchased Ransom Adam's homestead at the mouth of Gros Ventre Canyon and proceeded to convert the property to a dude ranch. Petzoldt constructed the lodge, barn, and a few cabins using logs harvested from the surrounding hills. The Ramshorn soon became one of Jackson Hole's most exclusive destination resorts.
