Central to Grand Teton National Park rises the Grand Teton, a 13,771 foot granite peak uplifted by movement starting 5-9 million years ago along a fault splitting the mountains and the valleys of Wyoming. The harsh lines of granite were further sculpted by ice, as years of glacial activity formed U-shaped canyons between the peaks, a process which continues today. The glaciers flowed into the valley floor, creating basins that are now filled by the beautiful Leigh, Jenny, Taggart, Phelps, and Jackson Lakes. This land abounds with a great beauty and a wide variety of wildlife.
