Grand Teton National Park owes its spectacular scenery to earthquakes. Born of earthquakes and sculpted by ice, it's an active and dynamic landscape. It boasts the youngest and steepest mountain range in the Rockies, contains some of the oldest rocks on earth, features glaciers, glacier-carved lakes, sagebrush flats, abundant and visible wildlife and a myriad of wildflowers.

This park approved audio tour is designed to be listened to while driving the inner and outer loops of Teton Park Road. The first half of the tour is "guided" and is synchronized with Teton Park Road, beginning at the Moose Visitor Center in the south and continuing north to Colter Bay. The second half is unstructured (unguided), ideal for completing the outer loop road (Hwy. 26/89/191) back to Moose or continuing north to Yellowstone. You'll enjoy unobstructed views of the Teton Range while listening to an impressive group of local experts. Geologists will explain the exciting geological processes that created the park's magnificent mountains, lakes and meadows. You'll be driving through open grasslands and will skirt dense forests, glacial lakes and marshy ponds -- putting you in close proximity to a variety of birds and animals. Therefore wildlife biologists and naturalists will tell you fascinating stories about their observations and experiences with the park's elk, moose, bear, bison and coyotes. You'll also hear from a park historian, who'll paint a clear picture of the areas' rich cultural history and bring to life the colorful characters who influenced the development of Grand Teton National Park.

Professionally narrated and filled with wonderful music and nature sounds, this 70-minute audio tour is as entertaining as it is educational.

This tour also includes an introduction to Yellowstone National Park. But if you'd like a complete understanding of both parks, get Travel Audios' tour of Yellowstone as well!
