Establishment of Grand Teton National Park June 21, 2008. Establishment of Grand Teton National Park The establishment of Grand Teton National Park took place over a period spanning more than 50 years. Located in the northwestern region of the U.S. state of Wyoming, Grand Teton National Park is south of Yellowstone National Park which was established in 1872, when Wyoming, Idaho and Montana were still territories and the region was very sparsely settled. By the late 19th century, conservationists were working to provide further protection to surrounding regions, leading President Grover Cleveland to create the Teton Forest Reserve, which included a portion of northern Jackson Hole.
