Montana Antiquities Database
The Montana Antiquities Database contains cultural resource information on known historic and archaeological sites, previously conducted cultural resource inventories, National Register site status, and cultural resource management project information. The database uses Oracle software and is housed at the Montana State Historic Preservation Office in Helena and the University of Montana Site Records Office in Missoula.
The database is divided into three parts:
- Cultural Resource Information System (CRIS)
- The CRIS portion of the database contains information on over 51,000 historic and archaeological sites within the State of Montana. It includes information on site type, owner, period, legal location, and numerous other data fields. CRIS is currently managed by the University of Montana Site Records Office. To request a Smithsonian number or a site form please contact the Site Records Office. A temporary CRIS form will need to be sent to receive a Smithsonian number. The SHPO requires Smithsonian numbers in order to process all consultation, including resolving APE, Eligibility, Effect etc., as it is the sole means of tracking properties.
