More than 30,000 young South Dakotans survived the Great Depression by working on public projects through the Civilian Conservation Corps. Many of them worked on bridges and trails, dams, facilities and parks in the Black Hills. Their legacy — including wonderful photos and an intensive directory of the workers — is preserved at a CCC Museum in the Hill City Visitor Information Center along Highway 16. Motorheads will love the ’35 GMC CCC truck on exhibit (behind glass), one of only 433 ever built. West of the Visitor Information Center is a lovely picnic spot, picturesquely bordered by a forest stream and a high granite outcropping.
