A Closer Look into the Appalachian Mountains

Welcome to one of North America’s most captivating natural wonders: the Appalachian Mountains. The Appalachian Mountains, stretching across the eastern region of North America, are known to be one of the biggest majestic natural wonders. This beauty has captivated explorers, scientists, and adventurers for centuries.

Historical Significance

The Aged Appalachian Mountains hold immense historical significance. Native American tribes, including the Cherokee, Shawnee, and Iroquois, have long inhabited these lands. European settlers arrived in the 17th century, pushing westward and establishing colonies along the eastern slopes. The Appalachian region became a frontier for exploration, trade, and conflicts, playing a pivotal role in shaping the history of North America.

The Birth of the Appalachians: A Journey of Discovery

The Appalachian Mountains’ story began roughly 480 million years ago, making them one of the oldest mountain ranges on Earth. To truly understand the age of the Appalachian Mountains, we must first delve into their origin. We are going all the way back to Ordovician Era and Paleozoic Era.

During the Paleozoic Era, a series of ancient continental collisions took place, and this process is known as Appalachian orogeny. These collisions formed a massive supercontinent called Pangea (the beginning of the age of dinosaurs).

Due to continental drift, the division and formation of landscape drastically changed. This geographical change was inevitable. The Appalachian Mountains went through a drastic change of nature. Hence it would be true to say that this magnificent landscape we get to witness today is not in its original form. This astonishing beauty went through a lot of geographical, volcanic-tectonic activities and continental fractures about 65 million years ago. The Appalachian Mountains were born as a result of the convergence of several tectonic plates.
