National Park Foundation | Grand Teton National Park:

The towering Tetons were formed from earthquakes that occurred over the past 13 million years along a fault line. The jagged range includes its signature peak Grand Teton, 13,770 feet (4,198 m) and at least twelve pinnacles over 12,000 feet (3,658 m). Seven morainal lakes adorn the base of the range, and more than 100 alpine lakes dot the backcountry.
