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. 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 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 grand teton national park on february 26, 1929.

gray wolves once were common throughout the rocky mountains. they were shot, poisoned, and trapped into local extinction by early settlers and federal agents. the last gray wolf in colorado was killed in 1940, and the wolf was first listed as an endangered species in 1967. wolves from southeastern british columbia recolonized northwestern montana in 1986; by 1994 the population had grown to 7 packs and about 70-75 wolves. wolves from glacier national park have dispersed naturally as far away as northeastern idaho and just south of yellowstone national park. a wolf was shot near yellowstone national park in 1992. from january to march 1995, 15 adult wolves from 7 different packs in canada were introduced into central idaho wilderness areas. several pairs have bred and produced the first litters of wolf pups born in idaho in more than 50 years. fourteen wolves (three family groups) were released in the yellowstone national park in late march 1995. a total of 66 wolves were released to the two areas in this manner in january 1995 and january 1996. several wolves from the northern rockies have dispersed to the southern rockies but have failed to establish a population there. most have been killed.
