Colossal Cave, AZ New Deal (2242)
One of many posters in the muserum desicribing the work of the "Colossal Cavemen" (the CCC). Colossal Cave is a Pima County park located about 20 miles southeast of Tucson. While the park is famous for its cave, it is also famous for much of the park having been built by the CCC -- which is the main reason I went to visit.
