The Archives will be closed Fridays until further notice.
The collections include documents from the military administration of the park (1886–1918), administrative records from the establishment of the National Park Service (1916) to the present, resource management records that document how the natural and cultural resources are protected, records of major projects that have occurred in the park, the records of park concessioners such as the Yellowstone Park Company, and donated manuscripts. The collection also contains historic maps, photographs, films, oral histories, administrative records, and scientific data.
The park is allowed to permanently hold federal records created by the park’s administration instead of transferring them to the National Archives because of its affiliation with the National Archives and Records Administration (NARA). While legal custody of these records belongs to NARA, physical custody is kept by Yellowstone National Park to allow researchers to have the best access to both current and historical resources in one location.
Notice to Researchers: Some collections will be temporarily closed due to an ongoing cataloging project. Contact the archives prior to planning a visit to ensure that the records you wish to consult will be available.
