Established as a state park in the early 1900s, Underhill State Park was incorporated into the larger Mt. Mansfield State Forest a few short years later. During the 1930s, the Civilian Conservation Corps (CCC), as a part of President Franklin Roosevelt’s New Deal program, descended upon the park. The CCC built the park office, restrooms, a picnic area, and a lodge. The lodge would later become a small hotel; however, it burnt down in the 1950s. The remaining structures are on the National Register of Historic Structures due to its historical significance and excellent conditions. The CCC also planted tens of thousands of Norway Spruce trees across Underhill State Park, which had been heavily logged.
