When the Civilian Conservation Corps was established in 1933, the state designated Mount Nebo State Park as one of the areas its local crews should work on. Over a two-year period, CCC crew 1780 developed significant portions of park infrastructure, including the construction of roads, bridges, cabins, hiking trails, and pavilions. The main pavilion, built by the CCC around 1935, was listed on the National Register of Historic Places in 1992. Ten of the surviving CCC-built cabins were also listed on the National Register in 2016, six individually and four as a group.
