Maryland Inventory of Historic Properties (Archaeology)

The Maryland Inventory of Historic Properties (MIHP) is the official inventory of both architectural and archaeological resources for the state of Maryland. There are currently over 13,000 archaeological sites on the MIHP, with more being added virtually daily.

Placing a Site on the MIHP

To register a site, a survey form must be completed and submitted to the Archaeological Registrar of the Maryland Historical Trust. These forms, and detailed instructions, are available for download below.

A Basic Data Form must be completed for all sites. There are three supplemental forms: an Historic Data Form for recording historic components, a Prehistoric Data Form for recording prehistoric components, and a Shipwreck Data Form for recording specific details of shipwrecks. If your site does not contain a shipwreck, you may delete the shipwreck form. Likewise, if it is only prehistoric or only historic, please delete the blank form.

If you have any questions, please contact the Archaeological Registrar, Jennifer Cosham, at (410) 697-9542.

When the form is complete, it must be submitted to the registrar in order to receive a site number. The preferred method of submittal is as a Microsoft Word document, emailed to The USGS quadrangle map, the sketch map, soil profiles, and any photographs you choose to include may either be pasted into the document itself or sent as separate email attachments.

If the file is too large to email, it is recommended that the graphics be sent separately. Large numbers of site forms or files of unusual size are requested on a CD. If digital submittal is not possible, the form may be printed and mailed to:

Jennifer K. Cosham
Archaeological Registrar
Maryland Historical Trust
Maryland Department of Planning
100 Community Place
Crownsville, MD 20132

Members of the public may record archaeological finds by contacting the Archaeological Registrar. Archaeological finds reported by members of the public or non-archaeological professionals are recorded as "Quad Files," and are available to professional archaeologists through the Medusa Cultural Resource Information System. You may use the Archaeological Find Reporting Form or simply send a map an explanatory paragraph. Photographs are gladly accepted but not required. A map, however, will be necessary to record the location.
