Located in south central, southeastern Montana and northwestern South Dakota the seven districts that make up the Custer Gallatin National Forest are rich in cultural and ecological diversity.  The Forest stretches from rugged high-country of the Absaroka-Beartooth Wilderness, the Gallatin Crest and vast portions of the Greater Yellowstone Ecosystem to the rolling landscapes and buttes of far southeastern Montana and northwestern South Dakota on the Ashland and Sioux Ranger Districts.
