Marine Fossils on Peaks? Burgess Shale to Rio Grande Rift - The Rockies Explained

Marine fossils at 2,400 meters. Granite rising 1,600 km from the coast. A rift that might one day split a continent. The Rockies are not what you think. From Yoho National Park’s Burgess Shale on Mount Stephen to Colorado’s tilted red sandstones, geologists reveal how ocean life ended up on alpine summits and why granite cores surfaced so far inland. Watch subduction turn “planetary traffic accidents” into mountains, see thrust faults stack ancient rock atop the new, and discover how a shallow-angled Pacific plate rewired North America’s interior. Clues from pollen grains, a K-Pg ash layer, and Denver’s buried “trash” date a rapid Rocky Mountain rise. Further south, the Rio Grande Rift thins the crust, fuels volcanoes, and vents CO2 and Helium-3 at hot springs, while GPS shows the rift slowly widening. Meanwhile, glaciers retreat across the Columbia Icefield as erosion reshapes the range grain by grain. If you’ve ever asked how the Rockies were born, why they still move, or what their future holds, this cinematic deep dive connects the proofs. Watch to the end for the surprising force that could redefine North America. #RockyMountains #PlateTectonics #BurgessShale #RioGrandeRift #Geology #Subduction #Glaciers #NakedScience
