Jackson is located in the scenic northwest corner of Wyoming. The town is surrounded by mountain ranges and nestled in a valley known as Jackson Hole, and gets the name "hole" from early trappers who primarily entered the valley from the north and east and had to descend down into the valley along relatively steep slopes, giving the sensation of entering a hole. The valley is named for David (Davey) Edward Jackson, a mountain man who trapped the area for beaver in the early nineteenth century. Though used by Native Americans for hunting and ceremonial purposes, the valley was not known to harbor year round human settlement prior to the 1870's.
Descriptions of the valley and its features were recorded in the journals of John Colter, who had been a member of the Lewis and Clark Expedition. After returning to the Rocky Mountains, Colter entered the region in 1806 in the vicinity of Togwotee Pass and became the first caucasian American to see the valley. His reports of the valley, the Teton Range and of the Yellowstone region to the north were viewed by people of the day with skepticism. 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 the much of the Teton Range as well as as Jackson Lake.
The town of Jackson, Wyoming, is at the southern end. 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. The average altitude of the valley is over 6,500 feet. High altitude and steep mountain slopes on all sides of the valley oftentimes causes calm winter nights to be very cold, as radiational cooling from snow-covered ground creates cold air near the surface, which then slides down into the valley due to its higher density. In 1993, this effect during an already severe cold snap plunged the morning low temperature down to -56°F or -53°C in the valley, officially recorded by the National Weather Service. The state record low temperature was also recorded in the valley at Moran at -66°F in 1933.
The only incorporated town in the valley is Jackson, sometimes also mistakenly called Jackson Hole. Other communities in the valley include Wilson, Teton Village, Moran Junction, Hoback, Moose (Moose Wilson Road, Wyoming), and Kelly. 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 tourism attractions throughout all seasons of the year.
