Built in 1939 by the Civilian Conservation Corps near Imnaha Springs in the Rogue River-Siskiyou National Forest, Imnaha Guard Station served as part of a network of remote guard stations that housed Forest Service workers close to summer job sites before roads were fully developed. It functioned as a barracks for firefighters and continued housing crews through the 1970s, later serving a resident family, volunteer hosts, and then public renters. Surrounded by relatively undisturbed old-growth forest and retaining its rustic design and outbuildings, it is notable for continuous summer use since construction, a rarity that helped secure National Register of Historic Places listing in 1991.
