How and When the Appalachian Mountains Formed - A Geological History

Embark on a 25-minute geological journey through the Blue Ridge province of the Appalachian Mountains to discover the ancient formation processes and diverse rock compositions of this mountain range. Learn about the three major mountain-building events, including a billion-year-old collision, that shaped these ancient peaks, and understand why they differ significantly from the Rocky Mountains. Explore various rock formations through detailed descriptions and analysis of geological maps, with special attention to the unique minerals that give the Blue Ridge its characteristic blue hue. Gain practical geological knowledge through field observations, rock identification, and comprehensive explanations of the region's complex geological history, from its active tectonic past to its current passive margin state.
