The CCC Company 947 Powder Magazine is a historic powder magazine in the eastern part of Ouachita National Forest. It is located in southern Yell County, about 200 yards (180 m) down a slope north of a ridge running parallel to Forest Road 71. The structure is made of stone and concrete, and is 6 feet (1.8 m) square and 5 feet (1.5 m) high, with a flat concrete roof and floor. The entrance is on the southeast side. The building was erected about 1933 by a crew of the Civilian Conservation Corps, and was used to store explosive materials used in the construction of roads and bridges in the area.
