In June 1960, Postmaster General Arther E. Summerfield announced a contract had been signed for the construction of a new post office building in the Hancock County community of Crystal Lake. Still in use today, the 520-square-feet post office was built to meet the latest standards including modern fluorescent lighting and equipment and a low, open service counter. The Crystal Lake Post Office, was one of 1,400 new post offices constructed across the nation in 1960.
