Located in the state of Wyoming (USA).
Grand Teton National Park is a national park in the United States, in the northwest of Wyoming. It has an area of about 130,000 hectares and includes most of the Titon mountain range and the northern part of the Jackson Hole Valley. Grand Teton is located just 16 km south of Yellowstone National Park. Two parks are connected by the territory known as the Memorial Alley named after John Davison Rockefeller, who is also managed by Grand Teton Park. The territories of both national parks, as well as the adjacent national forests and other environmental zones, form the Big Yellowstone ecosystem with an area of about 7.3 million ha, which is one of the largest preserved ecosystems in the world located in mid-latitudes.
