Civilian Conservation Corps promotional poster, 1939
The Civilian Conservation Corps was a federal work program created by President Franklin D. Roosevelt to alleviate unemployment during the Great Depression. Between 1933 and 1942, thousands of young Wisconsin men enlisted in the CCC. They lived in military-style barracks and worked on public landscape improvement projects including the construction of dams, bridges, trails and park shelters.
