Crater Lake National Park is a rare place of ineffable, distracting beauty. Its lake - Crater Lake - is remarkable. It is the deepest lake in the United States and the deepest volcanic lake in the world. The lake formed when Mount Mazama (one of the many ancient volcanic peaks that dot the landscape like a string of pearls stretching from British Columbia to Northern California) exploded in a violent eruption about 7,700 years ago.

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.
