Maryland Archaeological Conservation Laboratory

The Maryland Archaeological Conservation Laboratory (MAC Lab) is a archaeological research, conservation and curation facility located at Jefferson Patterson Park & Museum, the State Museum of Archaeology, in southern Maryland. The MAC Lab serves as a clearinghouse for archaeological collections recovered from projects conducted throughout Maryland, as well as collections from private donations (http://www.jefpat.org/mac_lab.html).

The digital records for the MAC Lab's collections are available here and are organized according to contributing installation. They are further organised by MAC Lab accession number and/or by archaeological site.

  • Out of the shadows…’: Examining Historic-Period Indian-made Ceramics Using Subtypological Analysis (2014)
    DOCUMENT Citation Only Valerie M.J. Hall.

    Maryland’s indigenous population, especially Indian women, transformed Early British American society during the 17th century. Maryland Indian women provided sustenance and crafts and served as cultural brokers, providing colonists with food and native-made goods, including aboriginal ceramics. Typing historic-period Native American ceramics in the Chesapeake region is challenging due to overlapping (and sometimes conflicting) typological attributes. Additionally, classifying wares by type...

  • Reassessing the Hallowes Site: Conflict and Settlement in the 17th-century Potomac Valley (2014)

    The John Hallowes Site in Westmoreland County, Virginia was excavated from 1968 to 1969. While no site report was written, an article summarizing the findings was published in Historical Archaeology in 1971. The artifacts from the site were not systematically catalogued until the 1980s, and it was not until 2010-2012 that an integrated study that compared the artifact data with site features, site history, regional archaeological findings, and regional history was completed. Benefiting from...

  • Tipping Point (2014)
    DOCUMENT Citation Only Julia King.

    As historical archaeologists in the Mid-Atlantic region of the US turn their focus not just to Europeans and Africans, sensu Deetz, but to the region’’s Indigenous people, emerging interpretations emphasize resistance and survival in the face of the European colonizing machine. These narratives are aimed at challenging the deeply entrenched notion of the disappearing Indian, but they also tend to ignore the losses, especially through displacement, experienced by Native people. Using...
