  • On February 26, 1929, Grand Teton National Park, in northwestern Wyoming, was created. Unlike nearby Yellowstone, Grand Teton took many years and much effort to become a national park
    As early as 1897, it was suggested that adding extra parkland to the south of Yellowstone would offer extra protection for migrating elk herds. Grand Teton originally only protected the peaks and glaciers, however. Residents, including ranchers, believed a national park would limit their business or alter their rural lifestyle.
    Eventually, a desire to preserve the beauty and history of the “Old West” inspired Wyomingites to support an expansion of the park. The addition of 14,164 hectares (35,000 acres) surrounding the mountains finally came about in 1950.
