The Appalachian Highlands is one of eight government-defined physiographic divisions of the contiguous United States.[1] It links with the Appalachian Uplands in Canada to make up the Appalachian Mountains. The Highlands includes seven physiographic provinces, which is the second level in the physiographic classification system in the United States. At the next level of physiographic classification, called section/subsection, there are 20 unique land areas with one of the provinces having no sections.[a]
The Appalachian Highlands are characterized by a diverse physiographic division.[2][3][4]
The seven provinces are:
- Adirondack
- Appalachian Plateau
- Blue Ridge
- Piedmont
- New England
- St. Lawrence
- Valley and Ridge
