The Mighty Rockies: Secrets of North America's Majestic Mountain Range

TLDRDiscover the fascinating story behind the formation of the Rocky Mountains, from their birthplace in Canada to their youngest peaks in the United States. Learn how ancient sea creatures ended up in mountain peaks and how plate collisions and erosion shaped this majestic mountain range.

Key insights

🏔️The Rockies stretch over 2,000 miles and are up to 300 miles wide, forming the backbone of North America.

🌊Ancient sea creatures now found in the Rockies lived and died in a shallow tropical sea over half a billion years ago.

🗻Thrust faulting pushed older layers of sedimentary rock up and over younger layers, forming the distinct peaks and valleys of the Rockies.

💦Erosion, including the power of glaciers, has sculpted the Rockies over millions of years, creating jagged cliffs and deep valleys.

🌄The Rockies continue to rise slowly and are constantly being shaped by tectonic forces and the elements.
