Appalachian Mountains
The Appalachian Mountains,[b] often called the Appalachians, are a mountain range in eastern to northeastern North America. Here, the term "Appalachian" refers to several different regions associated with the mountain range, and its surrounding terrain. The general definition used is one followed by the United States Geological Survey and the Geological Survey of Canada to describe the respective countries' physiographic regions. The U.S. uses the term Appalachian Highlands and Canada uses the term Appalachian Uplands; the Appalachian Mountains are not synonymous with the Appalachian Plateau, which is one of the provinces of the Appalachian Highlands.

The Appalachian range runs from the Island of Newfoundland in Canada, 2,050 mi (3,300 km) southwestward to Central Alabama in the United States;[c] south of Newfoundland, it crosses the 96-square mile archipelago of Saint Pierre and Miquelon, an overseas collectivity of France, meaning it is technically in three countries.[a][6] The highest peak of the mountain range is Mount Mitchell in North Carolina at 6,684 feet (2,037 m), which is also the highest point in the United States east of the Mississippi River.
The range is older than the other major mountain range in North America, the Rocky Mountains of the west. Some of the outcrops in the Appalachians contain rocks formed during the Precambrian era. The geologic processes that led to the formation of the Appalachian Mountains started 1.1 billion years ago. The first mountain range in the region was created when the continents of Laurentia and Amazonia collided, creating a supercontinent called Rodinia. The collision of these continents caused the rocks to be folded and faulted, creating the first mountains in the region.[4][7] Many of the rocks and minerals that were formed during that event can currently be seen at the surface of the present Appalachian range.[8] Around 480 million years ago, geologic processes began that led to three distinct orogenic eras that created much of the surface structure seen in today's Appalachians. [d] During this period, mountains once reached elevations similar to those of the Alps and the Rockies before natural erosion occurred over the last 240 million years leading to what is present today.[9]
The Appalachian Mountains are a barrier to east–west travel, as they form a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east–west. This barrier was extremely important in shaping the expansion of the United States in the colonial era.[10]
The range is the home of a very popular recreational feature, the Appalachian Trail. This is a 2,175-mile (3,500 km) hiking trail that runs all the way from Mount Katahdin in Maine to Springer Mountain in Georgia, passing over or past a large part of the Appalachian range. The International Appalachian Trail is an extension of this hiking trail into the Canadian portion of the Appalachian range in New Brunswick and Québec.
Appalachian Mountains' impact on North American History[edit]
Indigenous People[edit]
The roots of the Appalachian regions' histories trace back to the indigenous peoples who inhabited these lands long before European arrival. Indigenous communities across the Appalachians developed diverse cultures, languages, and societies, adapting to the region's varying environments and ecosystems. The interactions between indigenous communities and the natural world laid the foundation for the intricate relationship between humans and the Appalachian landscape.[49] Indigenous peoples thrived in these challenging terrains, adapting their lifestyles to the resources available. They forged deep connections with the land, developing sustainable practices for hunting, fishing, agriculture, and gathering. The Appalachian landscape provided a rich tapestry of flora and fauna, which indigenous communities learned to harness for their sustenance and well-being.[50] The Appalachian Mountains served as a conduit for trade networks, connecting distant indigenous communities through intricate trails. These trade routes facilitated the exchange of goods, ideas, and cultural practices across vast distances. This network fostered a sense of shared identity among diverse indigenous groups, transcending geographical boundaries.[51]
European Exploration[edit]
During the late 15th and early 16th centuries, European explorers embarked on voyages of discovery across the Atlantic Ocean. While seeking new trade routes and riches, they encountered the vast landmass of North America, including the Appalachian regions. The mountains posed a formidable geographical obstacle that European explorers had to navigate. The French, British, and Spanish were among the major powers vying for dominance in the New World, and their interactions with indigenous communities and the Appalachian landscape shaped the course of history.
