• Backbone State Park - Richland Township IA
    "The Civilian Conservation Corps (CCC) was established in April 1933 as a part of the New Deal Program of President Roosevelt as an effort to provide work for unemployed Americans during the Great Depression. Many of Backbone's buildings were constructed by the CCC from 1933 to 1941. Among the projects completed at Backbone were the dams on the Maquoketa River forming Backbone Lake, a cluster of rustic family cabins, beach and boat house, an auditorium, bridges, roads, picnic shelters, rest rooms, and trails. Most of these structures have been restored and the effort continues."
