Grand Teton National Park is located in the northwest corner of Wyoming. The Grand Teton Mountains include five connected mountains, namely the Central Teton Range, the South Teton Range, Mount Owen, the Teton Mountains and the Nez Perce Mountains, which occupy the center of the Teton Range. The mountains run from north to south. There are six lakes surrounding the foot of the Teton Range, which are connected by a Snake River. The Snake River is literally translated as "Snake River". It is 1,670 kilometers long and is one of the most important rivers in the Pacific Northwest of the United States. It originates near Yellowstone Park in Wyoming, flows westward through the Snake River Canyon, crosses the entire Idaho, and merges into the Columbia River in Washington State. Jackson Lake is the largest of the six lakes. The lake water mainly comes from the Snake River and the streams formed when the snow melts in the Grand Teton Mountains. It is the main source of water for agricultural irrigation in Idaho, which is its western neighbor. (Southeastern Idaho is the hometown of potatoes in the world. Idaho produces 30% of the potatoes in the United States in autumn. The production of peas and lentils in the north accounts for a large share in the United States.)
