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.

The Rosencrans Cabin Historic District is a three acre plot of ground in the Bridger-Teton National Forest east of Moran Junction. The district contains five log structures and the grave of forest ranger Rudolf ''Rosie'' Rosencrans. From this location Rosencrans rode horseback through Two Ocean Pass, the Upper Yellowstone and Thorofare country, and other areas of the forest which he administered in the early 1900s. Rosencrans built the first ranger station in the Bridger-Teton National Forest in 1915. The district is significant for its association with Rosencrans, who as one of the first rangers in the Forest, played an administrative role in the early history of the U.S. Forest Service.

The Snake River Land Company Residence and Office is the primary historic resource associated with J.D. Rockefeller and his Snake River Land Company located in Grand Teton National Park. Constructed as a private residence for well-to-do eastern politician John Hogan, the site was developed as a fox farm and small-scale guest ranch in 1926. The Snake River Land Company purchased the property in 1930 and used it as a base to manage the use and development of the company’s Jackson Hole properties.

The Squirrel Meadows Guard Station consists of a log cabin and frame outhouse in the Yellowstone Plateau of northwest Wyoming. The Guard Station locality was first designated as a Forest Service Administrative site in 1907. It is not known whether any buildings were built at that time, but the existing guard station is a replacement for an earlier facility. Construction of the cabin began in 1934. The Guard Station is significant for its ability to represent the characteristics of Forest Service administrative architecture during the 1930s, for its association with a rapid expansion of administrative facilities at that time, and as a rare building plan in Wyoming.

Located in Jackson, Wyoming, St. John's Episcopal Church is a one story log structure completed in 1916. St. John's Rectory was constructed in 1911 and is one of the largest and most significant log structures in all of Jackson Hole. The Church was an outgrowth of the mission work carried on in Jackson from 1908 to 1915. The role of the Episcopal Church in Jackson has always been a distinctive one. Services, church school, library facilities and Christian social gatherings added a great deal to the limited activities in town. The Rectory, or Hostel as it was originally called, was constructed under the guidance of Bishop Nathaniel Thomas. Episcopal church services were first held in Jackson in 1908, but with no regularity until the Rectory was built. Afterwards, priests came there not only to conduct services, but also to live. In the early years the hostel, or ''Rest House'' as it was often called, served in many capacities. Many ranchers and dudes of the early days were put up at the hostel because the ride to and from town was too long a trip for one day. The hostel has served as a community room or club room and was also used to accommodate primary classes when the population in the valley began to grow and the local schools became too crowded.

The String Lake Comfort Station is significant because it represents the National Park Service rustic style of architecture of the 1930s at Grand Teton National Park. It is one of three examples of this particular building type in the Park. The comfort station was built during the period 1934-1939 by either the Public Works Administration or the Civilian Conservation Corps for the National Park Service using Service developed plans for natural parks. Before its move to its present location the comfort station was located closer to the Jenny Lake Ranger Station, the main point of visitor contact at Grand Teton National Park until completion of the newer headquarters complex at Moose, Wyoming. The comfort station follows the practices typical of depression era rustic architecture as expressed in Grand Teton and other western parks.

The Brinkerhoff and the adjacent caretaker's cottage were built in 1946 at the end of World War II. The main lodge was designed by Jan Wilding and is considered to be of exceptional significance as the only extant example of the later development of the vacation home. The Brinkerhoff also has exceptional significance in that it represents the final period of private development on United States Forest Service leases within the modern park and is the last remaining example of a forest lease vacation home within Grand Teton National Park. At one time there were 111 such leases within the present Park boundaries. Its significance is furthered by the fact that after the National Park Service acquired the property during the late 1950s the lodge was converted to a VIP retreat housing such dignitaries as Richard M. Nixon and John F. Kennedy while they held public office. The presence of such dignitaries added to the favorable press the Park received after World War II and as a result further stimulated the tourist industry and park visitations. The Brinkerhoff also has exceptional significance in the area of rustic architecture and comes from the attempts of architect Wilding to update the rustic style into the post-World War II era.

The Snake River Ranch is a working ranch located on the west bank of the Snake River about five miles north of the town of Wilson, Wyoming. Although the cattle ranch covers considerable acreage, the ranch buildings are organized into three general complexes according to their function. From north to south along the river, these complexes are (1) Shop, (2) Headquarters, and (3) Residence. All except a few buildings were constructed during the 1930s and 1940s and retain a very impressive degree of integrity of structure, materials, workmanship, location, appearance, feeling, and association.

The ranch originated with the acquisition of two former homesteads, then owned by a neighboring rancher, by J. Walter Thompson Co. president Stanley B. Resor and his wife Helen Landsdowne Resor and was turned into both a vacation home for their family and a full-time, year-round cattle ranch. With its own sophisticated electrical generating facility, dairy barns, chicken and turkey coops, machine shops, and cattle and horse-related structures, the ranch became not only diversified and self-sustaining but by the end of 1950s its cattle operation had emerged as one of the most extensive and active ranches in the valley.

The Triangle X Barn is part of the outbuilding complex of the only dude ranch still in operation within Grand Teton National Park -- the National Park Service licensed Triangle X. Around 1928, J. C. Turner of the Triangle X Dude Ranch moved dovetailed logs from neighbor John Fee's partially completed homestead cabin to the Triangle X Ranch where the logs were used to form the first ten courses of Turner's new barn. The barn is a graphic visual representation of divergent notching types; a reminder of the extent to which resources are reused in a frontier economy; and an example of the close connection between vernacular, ''pioneer,'' architecture and its dude ranch successor.

The Upper Granite Canyon Patrol Cabin is located in the extreme southwestern corner of Grand Teton National Park, deep in Granite Canyon, and northwest of Teton Village. Like the cabins at Death Canyon, Cascade Canyon, and Moran Bay, this patrol cabin is significant for its association with National Park Service administration and development, and for its association with Park Service rustic architecture. It is thought that this cabin was constructed in 1935 by Civilian Conservation Corps crews as part of the larger backcountry trail/cabin network.

The Van Vleck House is a small one story log cabin located in Jackson, Wyoming. The building was built as a residential home in 1910-1911. The residential barn stands behind the house. Both structures are significant for their association with and representation of the earliest settlement of the town of Jackson in the early twentieth century. As the only original residential structures adjacent to the town square, the Van Vleck House and barn on the original lot represent the earliest history and development of this genuine old west agricultural community, which was later transformed by tourism.

The White Grass Dude Ranch historic district consists of ten guest cabins, a lodge, a dining hall, and a service/laundry building on the western edge of the White Grass Valley. The district buildings are all built in a style referred to as dude ranch vernacular. The historic district is significant because as a dude ranch it helped define and set the standards for the local Jackson Hole industry along with the Bar B C and J Y ranches. As a district it exemplifies the local development of dude ranches from cattle ranches in the area. The ranch was built during World War I as a cattle ranch, but by 1919 its owners, Hammond and Bispham, converted it to a dude ranch. After the conversion control of the property passed to Hammond's son-in-law Frank Galley who continued the operation until his death in 1985, making it the longest-lived active dude ranch in Jackson Hole.

The White Grass Ranger Station Historic District was built in 1930 using standardized plans of the National Park Service to be a backcountry ranger station for horse patrols during the early years of the Park's history. It was built at the western edge of the White Grass Valley southwest of Moose, Wyoming near a number of trail heads into the Teton Mountains which rise west of the district. The resources that make up the district include a cabin that functions as the ranger's office and quarters, a fire cache shed, a tack room shed, and a corral. The district was built in the rustic style as defined by the National Park Service. The district is the only example of the horse patrol era station extant in the Park.

The Wilson Commercial Historic District is locally significant under Criterion A for its association with Community Planning and Development and its association with Commerce. The district’s development origins can be traced back to Nicholas “Uncle Nick” Wilson’s 160-acre homestead established in 1895. Nick was responsible for the settlement of Wilson, and operated a small store, post office, boarding house and livery stable on his homestead. It was noted when he applied for his patent in 1904 that these developments were more of an accident than design, and that the small community of Wilson was not likely to be developed into a townsite. This early assessment turned true, and today Wilson is a census-designated place in Teton County. The townsite was never organized or incorporated. It grew from the haphazard series of necessities with a mixed residential and commercial use into a commercial corridor along Highway 22 where Wilsonites can satisfy basic needs without needing to travel into Jackson or over Teton Pass into Idaho. This growth is closely tied to the development of roads and safe passage over the formidable Snake River.

The Wort Hotel has been known as ''The Heart of Jackson'' since 1941 and continues to provide special Wyoming hospitality to visitors, old timers and newcomers of Jackson Hole. The Wort Hotel is located at the southeast corner of Broadway and Glenwood Streets, one block west of the internationally recognized elk antler arches on the Jackson Town Square. The building is an eclectic style reminiscent of Medieval architecture, most significantly Tudor, based on its peaked roof line, gabled wall dormers and decorative half timbers applied to the second story stucco. Locally, it is also described as a Swiss-Alpine style. The Silver Dollar Bar and Grill can be entered by a hallway leading from the hotel lobby. Jackson's famous watering hole got its name in 1950 when a hand-crafted elongated ''S'' shaped bar, inlaid with 2,032 uncirculated 1921 silver dollars was installed. Mounted above the bar, echoing its ''S'' shape are 13 panels of a burnt leather mural by well-known western artist, Paul Clowes. Each of the panels depicts an authentic episode of Jackson Hole history. The Wort Hotel was constructed by brothers John and Jess Wort in 1941 in honor of their father, Charles Wort, who in the early 1900s envisioned an elegant hotel in Jackson Hole to house tourists and visitors to the area. It became the first luxury hotel in the Jackson Hole valley and remains today a famous Jackson landmark.
