Grand Teton National Park

Grand Teton National Park is a United States National Park in northwestern Wyoming. At approximately 310,000 acres (130,000 ha), the park includes the major peaks of the 40-mile-long (64 km) Teton Range as well as most of the northern sections of the valley known as Jackson Hole. It is only 10 miles (16 km) south of Yellowstone National Park, to which it is connected by the National Park Service-managed John D. Rockefeller, Jr. Memorial Parkway. Along with surrounding National Forests, these three protected areas constitute the almost 18,000,000-acre (7,300,000 ha) Greater Yellowstone Ecosystem, one of the largest intact mid-latitude temperate ecosystems in the world.

Human history of the Grand Teton region dates back at least 11,000 years, when the first nomadic hunter-gatherer Paleo-Indians began migrating into the region during warmer months pursuing food and supplies. In the early 19th century, the first White explorers encountered the eastern Shoshone natives. Between 1810 and 1840, the region attracted fur trading companies that vied for control of the lucrative beaver pelt trade. U.S. Government expeditions to the region commenced in the mid-19th century as an offshoot of exploration in Yellowstone, with the first permanent white settlers in Jackson Hole arriving in the 1880s. Efforts to preserve the region as a national park commenced in the late 19th century, and in 1929 Grand Teton National Park was established, protecting the major peaks of the Teton Range. The valley of Jackson Hole remained in private ownership until the 1930s, when conservationists led by John D. Rockefeller, Jr. began purchasing land in Jackson Hole to be added to the existing national park. Against public opinion and with repeated Congressional efforts to repeal the measures, much of Jackson Hole was set aside for protection as Jackson Hole National Monument in 1943. The monument was abolished in 1950 and most of the monument land was added to Grand Teton National Park.
