Appalachian Highlands
The Appalachian Highlands is a major physiographic division of the United States, encompassing a complex geological and geographical landscape. This region is part of a larger system that includes the Appalachian Mountains, which stretch from the southeastern United States to the eastern parts of Canada. The term "Appalachian Highlands" is often used interchangeably with "Appalachian Uplands" in Canada, though the two terms refer to similar geographical features within their respective countries.
Geographical Scope
The Appalachian Highlands cover a vast area that includes multiple subranges and geographical features. These highlands are home to the Appalachian Plateau, a series of rugged, dissected plateaus located on the western side of the mountain range. The region also includes the Blue Ridge Mountains, known for their distinct bluish color when seen from a distance.
Geological Features
The geological history of the Appalachian Highlands is rich and varied. This region was formed over millions of years through several mountain-building events. The Geology of the Appalachians tells a story of ancient, eroded mountains that date back to before the formation of the Alps and the Rocky Mountains. These events have left behind a diverse array of geological formations, from steep ridges to deep valleys.
Ridge-and-Valley Appalachians
One notable feature within the Appalachian Highlands is the Ridge-and-Valley Appalachians, also known as the Ridge and Valley Province. This is characterized by long, parallel ridges and valleys that have been shaped by erosion over time.
Cultural and Economic Impact
The Appalachian Highlands have been home to many communities over the centuries, including various indigenous peoples and later, European settlers. The region has a rich cultural heritage, with the Appalachian culture being known for its unique music, folklore, and traditions.
Economically, the highlands have been significant for their natural resources, particularly coal and timber. The Appalachian Regional Commission plays a crucial role in promoting economic development and improving the quality of life in this region.
Appalachian Trail
A key feature of the Appalachian Highlands is the Appalachian Trail, a hiking trail that spans from Georgia to Maine, covering approximately 2,190 miles. This trail is a significant draw for outdoor enthusiasts and is maintained by organizations such as the Appalachian Mountain Club, one of the oldest conservation groups in the United States.
