Place: Grand Teton National Park, Wyoming

Towering more than a mile above the valley of Jackson Hole, the Grand Teton rises to 13,770 feet. Twelve Teton peaks reach above 12,000 feet and support a dozen mountain glaciers. The west side of the range slopes gently, showing the angle of tilt of the Earth's crust. The Teton Range is the youngest range in the Rockies and displays some of North America's oldest rocks.
