Jackson Hole, originally called Jackson's Hole, is a valley located in the U.S. state of Wyoming, near the western border with Idaho. The name "hole" derives from language used by early trappers or mountain men, who primarily entered the valley from the north and east and had to descend along relatively steep slopes, giving the sensation of entering a hole. These low-lying valleys are surrounded by mountains and contain rivers and streams, which were good habitat for beaver and other fur-bearing animals.
The valley is formed by the Teton Range on the western side and the Gros Ventre Range on the eastern side. Grand Teton National Park occupies the north-western part of the valley encompassing much of the Teton Range as well as Jackson Lake. The town of Jackson, Wyoming, is at the southern end. Between them lies, on U.S. Route 26, "Glacier View Turnout" offering a view of Teton Glacier on the north of Grand Teton,[2] and the National Elk Refuge, home of the largest elk herd on earth.
The Snake River threads through the entire valley from its headwater in Yellowstone in the north to the mouth of the Snake River Canyon at the southern tip of the valley. Blacktail Butte is a prominent landform rising from the valley floor. The average altitude of the valley is over 6,500 feet (2,000 m).
The only incorporated town in the valley is Jackson, sometimes also mistakenly called Jackson Hole itself. Other communities in the valley include Wilson, Teton Village, Moran Junction, Hoback, Moose (Moose Wilson Road), and Kelly. On the west side of the valley, Teton Pass crosses the Teton Range providing access to Victor and Driggs in eastern Idaho and Alta, Wyoming on the western side of the Tetons. Numerous elk use the valley as grazing range during the winter, and sleigh rides are offered to tourists. The Jackson Hole Mountain Resort, Snow King and Grand Targhee Resort ski areas, and nearby Grand Teton and Yellowstone national parks are major tourist attractions throughout all seasons of the year.
