The Gallatin National Forest (now known as the Custer-Gallatin National Forest) is a United States National Forest located in South-West Montana. Most of the Custer-Gallatin goes along the state's southern border, with some of it a part of North-West Wyoming.
Geography
The forest area comprises a total of 3,411,239 acres (13,804.79 km2) with around 2,129,194 acres (8,616.54 km2) located in the Gallatin Forest area and 1,282,045 acres (5,188.25 km2) within the Custer. Most of the Gallatin borders Yellowstone National Park and is a part of the Greater Yellowstone Ecosystem, an area which encompasses almost 20,000,000 acres (81,000 km2) in and around the park. The Custer National Forest is spread out along Eastern Montana and the North-West side of Wyoming, with most of its land being held in Montana.[3] The forest stretches through about six counties, including Park, Gallatin, Sweet Grass, Madison, Carbon, and Meagher.
There are six separate mountain ranges within the forest including the Gallatin, Madison, Bridger, Crazy, Absaroka, and Beartooth Ranges. The Beartooth's are home to Granite Peak, which at 12,799 ft (3,901 m), is the highest point both in the forest and in Montana. A separate section of the forest north of Livingston, Montana, is located in the Crazy Mountains which rise over 7,000 ft (2,100 m) above the Great Plains to the east. The forest includes two wilderness areas, the Absaroka–Beartooth and the Lee Metcalf, along with some of the tributaries for the Yellowstone, Madison, and Missouri rivers.
The forest is a cross roads and homelands of a number of Indian tribes, and subject to the treaties, cultural traditions and practices of various tribes.[5]
The forest was founded in 1899 as a part of the Northern U.S. Forest Service, eventually being named after Albert Gallatin (1761–1849), a U.S. Secretary of the Treasury and scholar of Native American languages and cultures.
In 1959, a 7.2-magnitude earthquake occurred in Madison Canyon outside of Yellowstone National Park, resulting in a massive landslide that blocked the Madison River and formed what we know as Quake Lake.
As of 2014, the Gallatin National Forest and Custer National Forest were merged administratively in order to combat rising costs, with a new management plan created for both national forests in 2020.[6]
There's access to the forest off Interstate 90 South on U.S. Highway 89 from Livingston, Montana, to Gardiner, Montana, or South on U.S. 191 from Bozeman, Montana, to West Yellowstone.
Over 2,290 mi (3,690 km) of hikingtrails are located in the forest providing access to wilderness areas and interlinking with trails in Yellowstone National Park. There are almost 40 vehicle accessible campgrounds scattered throughout the forest, numerous picnic areas, and even cabins that can be rented for a nominal fee through the forest's district offices. West Yellowstone, Montana provides access both into the forest and to Yellowstone National Park and is a popular snowmobile center during the winter. Nighttime temperatures can be below freezing any time of the year, and mosquitoes in the late spring and early summer are abundant. Summertime high temperatures average in the 70s Fahrenheit (21–26 °C), and the wintertime lows can drop below −40 degrees. Most of the precipitation falls in the form of snow with some places averaging over 33 ft (10 m) annually.
