Question: Clayton is located in which physiographic province of the larger Appalachian Mountains range

Context paragraphs:
Unaka Range: The Unaka Range is a mountain range on the border of Tennessee and North Carolina, in the southeastern United States.  It is a subrange of the Appalachian Mountains and is part of the Blue Ridge Mountains physiographic province.  The Unakas stretch approximately from the Nolichucky River to the south to the Watauga River to the north.  The Unakas include the prominent Roan Highlands, where several summits rise above 6,000 feet.  The Iron Mountains border the Unakas to the north, and the Bald Mountains border the Unakas opposite the Nolichucky to the south.  The name "unaka" is rooted in the Cherokee term "unega", meaning "white".

Maritime Plain: The Maritime Plain is a physiographic province of the larger Appalachian division.  The Maritime Plain runs around the coast of New Brunswick and Nova Scotia from the south shore of Chaleur Bay and includes Prince Edward Island and the Magdalen Islands.  The Kouchibouguac National Park lies in the New Brunswick lowlands, part of the Maritime Plain.

Piedmont (United States): The Piedmont is a plateau region located in the eastern United States.  It sits between the Atlantic Coastal Plain and the main Appalachian Mountains, stretching from New Jersey in the north to central Alabama in the south.  The Piedmont Province is a physiographic province of the larger Appalachian division which consists of the Piedmont Upland and the Piedmont Lowlands sections.

Clayton, Georgia: Clayton is a city in Rabun County, Georgia, United States.  The population was 2,019 at the 2000 census.  The city is the county seat of Rabun County and is located in the Blue Ridge Mountains.

New England province: The New England province is a physiographic province of the larger Appalachian division of eastern North America.  The province consists of the Seaboard Lowland, New England Upland, White Mountain, Green Mountain, and Taconic sections.

Wallkill Valley: The Wallkill Valley is a broad valley extending through southeastern New York and northwestern New Jersey.  It is composed of rolling hills, plains, and swamps (including the Black Dirt Region) surrounding the Wallkill River.  The valley is a subdivision of the larger Hudson Valley, bound to the west by the Shawangunk Ridge/Kittatinny Mountains and to the east by the Marlboro Mountains and New York–New Jersey Highlands.  The northern Wallkill Valley is sometimes associated with the greater Catskills region, although it is geographically separated from the Catskill Mountains by the Shawangunk Ridge and Rondout Valley.  In a broader sense, the Wallkill Valley is part of the Ridge-and-Valley physiographic province of the Appalachian Mountains, while the Catskills further to the north and west are part of the Appalachian Plateau.

Ridge-and-Valley Appalachians: The Ridge-and-Valley Appalachians, also called the Ridge and Valley Province or the Valley and Ridge Appalachians, are a physiographic province of the larger Appalachian division and are also a belt within the Appalachian Mountains extending from southeastern New York through northwestern New Jersey, westward into Pennsylvania and southward into Maryland, West Virginia, Virginia, Kentucky, Tennessee, Georgia and Alabama.  They form a broad arc between the Blue Ridge Mountains and the Appalachian Plateau physiographic province (the Allegheny and Cumberland Plateaus).  They are characterized by long, even ridges, with long, continuous valleys in between.

Great Smoky Mountains: 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.

Notre Dame and Mégantic Mountains: The Notre Dame and Mégantic Mountains in Canada are a physiographic province of the larger Appalachian division, and also contain the Chic-Choc Mountains.  The Notre Dame Mountains rise to a level of approximately 2000 ft above sea level and extend southwest to northeast, south of the Saint Lawrence River.  The abundant mineral resources in this region have resulted in a unique mining landscape.  The Notre Dame Mountains extend 500 mi from the Green Mountains of Vermont into the Gaspé Peninsula, Quebec.

Blue Ridge Mountains: The Blue Ridge Mountains are a physiographic province of the larger Appalachian Mountains range.  This province consists of northern and southern physiographic regions, which divide near the Roanoke River gap.  The mountain range is located in the eastern United States, starting at its southernmost portion in Georgia, then ending northward in Pennsylvania.  To the west of the Blue Ridge, between it and the bulk of the Appalachians, lies the Great Appalachian Valley, bordered on the west by the Ridge and Valley province of the Appalachian range.
