Crazy Mountain National Forest
Crazy Mountain National Forest was a United States National Forest in Montana. It was established as the Crazy Mountain Forest Reserve by the U.S. Forest Service on August 10, 1906, with 234,760 acres (950.0 km2), and became a National Forest on March 4, 1907. On July 1, 1908, it was combined with part of Yellowstone National Forest to re-establish Absaroka National Forest, and its name was discontinued.
The forest was part of the Jefferson Division of Lewis and Clark National Forest. The Crazy Mountains were included in the unit, primarily in Meagher County.
