<P> 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 10 miles ( 16 km ) 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 . By 1902 , the reserve had been combined into the Yellowstone Forest Reserve , then was divided again in 1908 by President Theodore Roosevelt , establishing the Teton National Forest , which protected most of the Teton Range . By 1907 , the U.S. Bureau of Reclamation had constructed a temporary dam at the Snake River outlet of Jackson Lake . This dam failed in 1910 and a new concrete Jackson Lake Dam replaced it by 1911 . The dam was further enlarged in 1916 , raising lake waters 39 ft ( 12 m ) as part of the Minidoka Project , designed to provide irrigation for agriculture in the state of Idaho . Though efforts to protect the Teton Range and Jackson Hole as part of an expanded Yellowstone National Park dated back to the late 19th century , proposals to construct more dams on some of the other lakes in Jackson Hole led Yellowstone National Park superintendent Horace Albright to block such efforts . Albright was originally an advocate of the expanded Yellowstone plan which was very unpopular with local residents . By the mid-1920s local sentiment had changed as a result of proposals for a new national park including only the Teton Range and six lakes at the base of the range . With the general agreement of prominent Jackson Hole residents to this plan , President Calvin Coolidge signed the executive order establishing the 96,000 - acre ( 39,000 ha ) Grand Teton National Park on February 26 , 1929 . </P>
