Grand Teton National Park
The Teton Range towers over Jackson Hole. Powerful geologic forces began stretching this area less than 10 million years ago cracking the Earth's crust to form the 40-mile long Teton fault. Movement on this fault generates massive earthquakes up to magnitude 7.5. Each earthquake hinges the mountain block skyward and drops the valley-block leaving no foothills.Ancient granite and gneiss, 2.5 to 2.7 billion years ago, from the core of this youthful range. These rocks resist erosion but over time wind, water and ice slowly shape the landscape. Ice, in the form of glaciers, carved and sculpted the dramatic landscape forming jagged arêtes, U-shaped canyons and deposited moraines. "The grand lift of the Tetons is more than a mechanistic fold and faulting of the earth's crust; it becomes a primal gesture of the earth beneath a great sky."| HM Number | HM1NZI |
