 The Veterans Conservation Corps—a branch of the Civilian Conservation Corps for unemployed World War I veterans—had a major camp at nearby Sibley State Park, so a side camp was established at Monson Lake in 1936.The VCC men constructed a Sanitation Building and a Combination Building (a picnic shelter with a public cooking area and space for a concession service).These were built in the National Park Service rustic style with local granite and white oak.
