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.
