Episodes

1. Yellowstone: Microcosm of the National Parks

30m

Start your tour of the geological wonders of North America's national parks with Yellowstone, where the breathtaking landscape inspired the idea of a national park. Focus on the processes that produce Yellowstone's many geothermal formations, particularly its geysers.

2. Yellowstone's Cataclysmic Origins and Future

30m

Read the evidence in the rocks to discover Yellowstone's bigger story: the massive volcanic eruptions that created the region and will one day destroy it, the glaciers that shaped the terrain, and the meltwater floods that carved the impressive Grand Canyon of Yellowstone.

3. Grand Teton and Jackson Hole

30m

At Grand Teton National Park south of Yellowstone, an active fault lifts some of North America's oldest rocks to the summits of some of the continent's youngest mountains. Explore these glacier-sculpted peaks, and learn the origin of the broad valley, called Jackson Hole, at the base of the Teton Range.

4. Hawaii Volcanoes: Earth's Largest Mountains

30m

Compare the lessons of hotspot volcanism at Yellowstone with the very different landscape at Hawaii Volcanoes National Park, which is also stoked by upwelling magma from Earth's mantle. Professor Cochran describes rivers of fire on the Big Island of Hawaii and suggests distinctive lava formations to visit.

5. The Hawaiian Islands and Maui's Haleakala

30m

How does a barren volcanic landscape become a tropical paradise? Study the speed with which volcanic islands erode, leaving rich soil behind. Watch these processes at work on the Big Island of Hawaii, at Haleakala National Park on Maui, and also in the National Park of American Samoa.

6. Mount Saint Helens, Lassen Volcanic, Rainier

30m

Tour Mount Rainier National Park and Lassen Volcanic National Park in the Pacific Northwest, which are part of the Cascade Range of active volcanoes that include Mount Saint Helens. Then visit a group of similarly cataclysmic volcanoes in national parks in central Mexico.

7. Crater Lake, Olympic, North Cascades

30m

Learn how seafloor subduction raised a lofty volcano only to obliterate it in a colossal eruption that created Crater Lake in Oregon. Hundreds of miles to the north, tectonic forces upended the imposing mountains of Olympic National Park and formed the high jagged peaks at North Cascades National Park.

8. Volcanoes of Alaska: Katmai and Lake Clark

30m

Travel to Alaska to explore the vast national parks at Katmai and Lake Clark. Katmai was the site of the 20th century's largest volcanic eruption, while Lake Clark is unusual among national parks for having no roads and being accessible only by boat or small plane.

9. Alaska's Glacier Bay and Kenai Fjords

30m

Continue your tour of the largest state with stops at two spectacular parks that are popular destinations for cruise ships: Glacier Bay and Kenai Fjords. Discover how glaciers form and examine their historical advance and retreat in this region. Also, learn how a glacier is like a candy bar!

10. Yosemite: Nature's Cathedral

30m

Survey the most beautiful valley on Earth: Yosemite. Even for those who have not yet visited, its views are iconic thanks to stunning photos by Ansel Adams and others. Investigate the geological history of the park, focusing on its most distinctive rock type-granite.
