Archeologists have evidence that the first humans arrived in the Jackson Hole valley about 11,000 years ago. They lived in the valley from spring to fall but left during the winters. Eight peaks towering above 12,000 feet exist within the park. The highest peak, the Grand Teton, rises 13,770 feet above sea level.

How was Grand Teton formed?
A 2.7 billion-year old metamorphic rock called gneiss makes up much of the Teton Range. These rocks were formed when sea floor sediments and volcanic debris were buried up to 18 miles deep as two tectonic plates collided – similar to the collision of India and Asia today forming the Himalayas.

How did the Teton fault move?
Rates of movement on the fault have changed throughout time. At the end of the Pinedale glaciation 16,000 to 14,000 years ago, slip on the fault increased. This was likely due to changing stresses on the fault as glaciers melted.
What type of mountain is the Tetons?
1 and 52). The Tetons are a still different kind—a fault block mountain range carved from a segment of the earth's crust that has been uplifted along a fault.
What type of stress created the Grand Tetons?
About 10 million years ago, Earth's crust started to stretch and thin, forming faults and causing earthquakes. Over time, the block of earth west of the Teton fault shot upward, forming the Tetons, and the block of earth east of the fault dropped more than 6,000 meters (20,000 feet) forming the valley.

How fast are the Grand Tetons growing?
The summit of the Grand is, essentially, where it has always been. Geologists reckon the mountain is growing at a very slow rate due to the upthrust of the Teton Fault. That growth is on the order of perhaps a millimeter a year, or perhaps 5 1/2 inches since Hayden.
How old is the Teton Glacier?
Over the last 10,000 to 160,000 years, melting and receding glaciers created much of the Jackson Hole and Grand Teton National Park landscapes we know today. In thirty years, it's likely some of the park's glaciers will be history. Does it matter?
