The Birth of a Mountain: The Taconic and Acadian Orogenies The formation of the Appalachians did not happen all at once; it was a multi-stage process driven by the breakup and reassembly of ancient continents. The Role of Erosion: Shaping the Modern Landscape While tectonic forces built the mountains, it was erosion that defined their current appearance.
Gondwana North America Collision: Shaping the Appalachian Mountains
The initial building phase began roughly 480 million years ago during the Ordovician period, in an event known as the Taconic Orogeny. A chain of volcanic islands, located near the equator, began to collide with the North American continent.
The collision that created the Appalachians was the result of the northward movement of the supercontinent Gondwana—what is now Africa—crashing into what is now North America. The story of how the Appalachian Mountains were formed is a saga written in the language of geology, spanning hundreds of millions of years.

Rivers carved deep, V-shaped valleys into the landscape, isolating the more resistant rock layers as "hogsbacks" or ridges, while leaving the softer rock behind as valleys.
