Jackson Hole is a valley in the U.S. state of Wyoming. It is located in west-central Wyoming, 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 white 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.

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. In many parts of the world, winter is associated with snow. ...
