Jackson Hole is a broad mountain valley in northwestern Wyoming between the Teton and Gros Ventre ranges, named from an old trapping term for a stream-watered valley enclosed by mountains and later associated with trapper David Edward "Davy" Jackson. Shaped as a geologic graben and crossed by the Snake River, it includes part of Grand Teton National Park and is known for dramatic alpine scenery and severe winter cold. Native Americans long used the valley for hunting and ceremonies, and John Colter gave the first recorded European-American description in 1807. Unsuitable for crops, it developed around cattle grazing, then tourism, and is now a major recreation, travel, and cultural destination.
