Overview
Course No. 1707
From Yellowstone to the Everglades, join geologist and National Geographic director Ford Cochran on a fascinating scientific tour of all of America’s national parks.
There’s no better education in Earth’s geological forces than North America’s national parks. These 36 lectures reveal the dramatic stories hidden beneath the scenic vistas—from colliding tectonic plates that built mountain ranges, to glaciers that carved valleys, to volcanoes that reshaped entire regions. Covering every U.S. national park plus exceptional preserves in Canada and Mexico, this course explores:
- Cataclysmic origins of Yellowstone’s supervolcano and Hawaii’s lava flows
- Ancient collisions that created the Appalachians and Rockies
- Erosive power behind the Grand Canyon and Badlands formations
- Unique ecosystems from coral reefs to giant sequoia forests
No scientific background needed—just curiosity to uncover how these iconic landscapes formed over billions of years. Perfect for travelers and armchair explorers alike!
