Access the Office of Archaeology & Historic Preservation (OAHP) cultural resource files?
Unfortunately not all of the Colorado Office of Archaeology and Historic Preservation records are available to everyone. Please refer to our policies and procedures (PDF) for more information.
Although OAHP restricts access to various types of cultural resource data, we also recognize the need to use this information. It is the intent of the policies and procedures to responsibly control and document access without impeding the appropriate use of the files, therefore:
The File Access Request form must be completed whenever cultural resource files are accessed. This includes site/property forms, documents, maps, and images of any kind. If you are planning to visit OAHP to do research we strongly encourage you to complete the File Access Request form available in fillable PDF format and send it to us prior to your visit. This will allow the staff, when possible, to have the requested materials ready for you when you arrive. You can:
mail it (History Colorado Center, Office of Archaeology and Historic Preservation, 1200 Broadway, Denver, CO 80203)
You can also complete the form while at the office.
OAHP staff will pull the appropriate information for the visitor. The files are not accessible to non-staff.
Individuals requesting restricted materials who are not known by the OAHP staff may need to submit qualifications in advance for our review. If you have new staff who will be visiting the office please contact us prior to their visit.
Please let us know if you have any questions or comments.
