Newfound Gap (el. ) is a mountain pass located near the center of the Great Smoky Mountains National Park of the southern Appalachian Mountains in the United States of America. Situated along the border of Tennessee and North Carolina, the state line crosses the gap, as does Newfound Gap Road (which overlaps U.S. Route 441 through the park and ends at the park's boundaries near Gatlinburg, Tennessee and Cherokee, North Carolina). The Appalachian Trail also traverses the gap, as do a small number of other hiking trails. Newfound Gap is also home to the Rockefeller Memorial, a popular destination within the national park and the site from where former U.S. President Franklin D. Roosevelt formally dedicated the park on September 2, 1940. According to the National Weather Service, Newfound Gap has around 19 snowy days per year. From 1991 to 2005, annual snowfall ranged from to . History Prior to the development of the Great Smoky Mountains National Park, Newfound Gap was an undiscovered pass two miles east of what was long thought to be the lowest mountain pass over the Great Smoky Mountains, Indian Gap. Indian Gap Road, an unpaved, arduous trail frequented by traders, farmers, and even by the Confederate Army during the American Civil War, was completed in 1839 and named after the old Cherokee Indian trail that the road paralleled. Newfound Gap itself was not recognized as the lowest gap over the mountains until 1872, when Arnold Guyot measured many of the mountains in the area and determined the "Newfound Gap" to be a lower, more accessible mountain pass. Climate Newfound Gap Road With the development of the Great Smoky Mountains National Park came the construction of a newer, more modern highway from Tennessee to North Carolina, completed in 1932 – this time crossing Newfound Gap, replacing the now-defunct Indian Gap Road. North of the park, it is now known as Great Smoky Mountains Parkway. The Gatlinburg Bypass, originally intended to be a part of the Foothills Parkway, extends out from the park to connect Newfound Gap Road south of town to the parkway north of town. Despite its heavy winter snows, the pass is kept open all year, except during and just after winter storms. When closed, the snow route is a long detour around the east-northeast end of the park, using U.S. 321 and Interstate 40. The Tennessee side typically has heavier snow because
