Gates of the Mountains Wilderness
The Gates of the Mountains Wilderness is located in the U.S. state of Montana. Created by an act of Congress in 1964, the wilderness is managed by Helena National Forest. A day use campground near the Gates of the Mountains, Meriwether Picnic site, is named in honor of Meriwether Lewis.
Gates of the Mountains Wilderness was the site of the 1949 Mann Gulch fire, which claimed the lives of 13 firefighters and which was the subject of Norman Maclean's book Young Men and Fire.
U.S. Wilderness Areas do not allow motorized or mechanized vehicles, including bicycles. Although camping and fishing are allowed with proper permit, no roads or buildings are constructed and there is also no logging or mining, in compliance with the 1964 Wilderness Act. Wilderness areas within National Forests and Bureau of Land Management areas also allow hunting in season.
History
The Gates of the Mountains Wilderness were named by Lewis and Clark. Captain Lewis wrote on July 19, 1805,In 1918, when Holter Dam was built forming Holter Lake, the water level of the Missouri River in the Gates was raised approximately.
The Gates of the Mountains area was considered multiple times for inclusion in the national park system. In 1922, Montana senator Thomas J. Walsh suggested the idea to National Park Service director Stephen Mather, writing, "you must be familiar with the locality and with the wonderfully graphic account of its marvels and beauties found in the journal of Lewis and Clark." Mather visited the site but decided that it lacked national significance and that local or state protection would be adequate to preserve it. The NPS dropped the proposal at the end of 1922, only to reconsider it in 1935 and again in the 1960s. Both times, officials reached the same conclusion: "The area is suitable for a county park or a state park." The area received its wilderness designation under the Wilderness Act of 1964.
