In 1905, the Elkhorn Forest Reserve was formed and between this date and the forming of the Helena National Forest in 1908, the Eagle Cabin was taken over by the U.S. Forest Service for administrative use. Eagle, Tizer and Glendale stations were all tied together by a telephone line that went into a switchboard at the store in Radersburg. The cabin is the oldest administrative log structure on the Helena National Forest and, in fact, predates the establishment of the Forest. Eagle was used by the Forest Service on a regular basis until the early 1950s. Riders from the Crow and Indian Creek Livestock Association used the cabin over the years up until the 1970s.
