Question: The John Messer Barn is a historic structure within the Great Smoky Mountains National Park in Sevier County, Tennessee, this barn is a different Messer Barn in which valley, in the Great Smoky Mountains of North Carolina, located in the Southeastern United States?
Context: Oconaluftee is the name of a river valley in the Great Smoky Mountains of North Carolina, located in the Southeastern United States.  Formerly the site of a Cherokee village and Appalachian community, the valley's bottomland is now home to the main entrance to the North Carolina side of the Great Smoky Mountains National Park. Elkmont is a region situated in the upper Little River Valley of the Great Smoky Mountains of Sevier County, in the U.S. state of Tennessee.  Throughout its history, the valley has been home to a pioneer Appalachian community, a logging town, and a resort community.  Today, Elkmont is home to a large campground, ranger station, and historic district maintained by the Great Smoky Mountains National Park. The Walker Sisters Place was a homestead in the Great Smoky Mountains of Sevier County, in the U.S. state of Tennessee.  The surviving structures— which include the cabin, springhouse, and corn crib— were once part of a farm that belonged to the Walker Sisters— five spinster sisters who became local legends due to their adherence to traditional ways of living.  The sisters inherited the farm from their father, and after the Great Smoky Mountains National Park was formed in the 1930s, they obtained a lifetime lease.  The National Park Service gained control of the property in 1964 when the last Walker sister died.  The surviving structures were placed on the National Register of Historic Places in 1976. The Tyson McCarter Place was a homestead located in the Great Smoky Mountains of Sevier County, in the U.S. state of Tennessee.  Before the establishment of the Great Smoky Mountains National Park in the 1930s, the homestead belonged to mountain farmer Jacob Tyson McCarter (1878–1950), a descendant of some of the area's earliest European settlers.  While McCarter's house is no longer standing, several outbuildings— including a barn, springhouse, corn crib, and smokehouse— have survived, and have been placed on the National Register of Historic Places. The Noah "Bud" Ogle Place was a homestead located in the Great Smoky Mountains of Sevier County, in the U.S. state of Tennessee.  The homestead presently consists of a cabin, barn, and tub mill built by mountain farmer Noah "Bud" Ogle (1863–1913) in the late 19th century.  In 1977, the homestead was added to the National Register of Historic Places and is currently maintained by the Great Smoky Mountains National Park. The Meigs Mountain Trail is an American hiking trail in the Great Smoky Mountains National Park of Sevier County, Tennessee.  The trail traverses the northern slopes of Meigs Mountain in the northwest section of the park, connecting Jakes Creek in the Elkmont area with Lumber Ridge in the Tremont area.  The Meigs Mountain Trail, when joined with the 4.1 mi Lumber Ridge Trail and the first 0.4 mi of the Jakes Creek Trail, is part of a 10.5 mi continuous path connecting the Appalachian Club section of Elkmont with the Great Smoky Mountains Institute at Tremont.  In the early 20th century, the logging communities that formed at Elkmont and Tremont branched out across the relatively broad northern slopes of Meigs Mountain.  Other than a crude mountain cemetery, the occasional detritus, and a few rock walls, however, very little remains of the mountain's former inhabitants. The Blue Ridge Parkway is a National Parkway and All-American Road in the United States, noted for its scenic beauty.  The parkway, which is America's longest linear park, runs for 469 mi through 29 Virginia and North Carolina counties, linking Shenandoah National Park to Great Smoky Mountains National Park.  It runs mostly along the spine of the Blue Ridge, a major mountain chain that is part of the Appalachian Mountains.  Its southern terminus is at U.S. 441 on the boundary between Great Smoky Mountains National Park and the Cherokee Indian Reservation in North Carolina, from which it travels north to Shenandoah National Park in Virginia.  The roadway continues through Shenandoah as Skyline Drive, a similar scenic road which is managed by a different National Park Service unit. The Great Smoky Mountains are a mountain range rising along the Tennessee–North Carolina border in the southeastern United States.  They are a subrange of the Appalachian Mountains, and form part of the Blue Ridge Physiographic Province.  The range is sometimes called the Smoky Mountains and the name is commonly shortened to the Smokies.  The Great Smokies are best known as the home of the Great Smoky Mountains National Park, which protects most of the range.  The park was established in 1934, and, with over 9 million visits per year, it is the most-visited national park in the United States. Cataloochee is a valley in the Great Smoky Mountains of North Carolina, located in the Southeastern United States.  Now a recreational and historic area within the Great Smoky Mountains National Park, Cataloochee was once home to a substantial Appalachian community and Cherokee hunting ground. The John Messer Barn is a historic structure within the Great Smoky Mountains National Park in Sevier County, Tennessee, United States.  Located along the Porters Creek Trail in the Greenbrier valley, it was constructed in 1875 by Pinkney Whaley.  The Whaleys later sold their farm to John H. Messer, who was married to Pinkney's cousin, Lucy.  In the 1930s, the Smoky Mountain Hiking Club, which constructed the Smoky Mountain Hiking Club Cabin nearby, leased the barn from the National Park Service.  The barn was added to the National Register of Historic Places in 1976, and is the last surviving structure from the pre-park Greenbrier Cove community.  This barn should not be confused with the Messer Barn in Cataloochee, which was built by John's cousin, Will Messer.
