The State Historical Society of North Dakota acquired Camp Hancock in 1951 for preservation as a state historic site and began repairing fire damage to the lone remaining structure, the officers quarters from the 1870s, later used as the U.S. Weather Bureau office for North Dakota. The building opened as a museum in 1955, and a recently retired Northern Pacific Railway steam locomotive was moved onto the site to honor the railroad's role in the creation of Camp Hancock and the city of Bismarck in 1872. In 1965 the city's oldest church, the Bread of Life Church, later renamed St. George Episcopal, was moved to the site; it had been in use from 1881 to 1949 and was connected with many events in Bismarck's history. Camp Hancock is listed in the National Register of Historic Places. The site includes the current museum, formerly officers' quarters from 1872 to 1877, quartermaster's office and signal station from 1877 to 1894, and Weather Bureau offices from 1894 to 1940; a U.S. Weather Bureau Cotton Region Instrument Shelter; the 1881 Church of the Bread of Life; a U.S. Coast and Geodetic Survey marker; the former U.S. Weather Bureau rotunda and goldfish pond; a 1909 Northern Pacific Railway steam locomotive; a State Historical Society of Northern Dakota maintenance shop; the August 1872 Camp Greeley location; commanding officer's quarters from 1872 to 1877, quartermaster's residence from 1877 to the 1890s, and Weather Bureau station chief residence from 1894 to the 1920s; original barracks and mess rooms from 1972 to 1875; a barracks addition from about 1875 that included a kitchen, bakery, dispensary, hospital, laundry, and carpentry shop; and warehouses from the 1880s.
