The west block along the fault line rose to form the Teton Range, creating the youngest mountain range in the Rocky Mountains. The fault's east block fell to form the valley called Jackson Hole. The geological processes that led to the current composition of the oldest rocks in the Teton Range began about 2.5 billion years ago.
Grand Teton National Park is a national park of the United States in northwestern Wyoming.At approximately 310,000 acres (1,300 km 2), the park includes the major peaks of the 40-mile-long (64 km) Teton Range as well as most of the northern sections of the valley known as Jackson Hole.
Looking west, the Teton Range rises more than 7,000 feet (2,130 m) above the valley floor with its iconic John Moulton Barn.. Jackson Hole (originally called Jackson's Hole by mountain men) is a valley between the Gros Ventre and Teton mountain ranges in the U.S. state of Wyoming, near the border with Idaho, in Teton County.

Paleo-Indian presence along the shores of Jackson Lake is attested from 11,000 years ago in what is now Grand Teton National Park. [9] Jackson Hole valley climate at that time was colder and more alpine than the semi-arid climate found today, and the first humans were migratory hunter-gatherers spending summer months in Jackson Hole and wintering in the valleys west of the Teton Range.
The geology of the Grand Teton area consists of some of the oldest rocks and one of the youngest mountain ranges in North America. The Teton Range, partly located in Grand Teton National Park, started to grow some 9 million years ago. An older feature, Jackson Hole, is a basin that sits aside the range.

The lake is the remnant of large glacial gouging from the neighboring Teton Range to the west and the Yellowstone Plateau to the north. [5] The lake is primarily fed by the Snake River, which flows in from the north, and empties at Jackson Lake Dam. Jackson Lake is one of the largest high altitude lakes in the United States, at an elevation of ...
