Volunteers work at the Billingsley site Volunteers work at the Billingsley site.

The Maryland Historical Trust (MHT) works with partner agencies, organizations, and volunteers to identify, study, evaluate, preserve, protect, and interpret the state's archaeological heritage. As part of this work, MHT surveys and documents archaeological sites, issues permits for archaeology, reviews state and federal projects, and offers programs to help connect the public to Maryland archaeology. MHT maintains archaeological data in Medusa, the state's cultural resource information system, and makes that data available to qualified researchers. MHT also provides technical assistance and grant opportunities to those interested in archaeological research in Maryland.

At MHT's headquarters in Crownsville, archaeology is organized into two major program areas: terrestrial archaeology, which carries out land-based survey and lab research, and maritime archaeology, which focuses on submerged (underwater) cultural resources in Maryland state waters. MHT's archaeology priorities are informed by public input and outlined in each update of the statewide preservation plan.

In Calvert County, Jefferson Patterson Park and Museum houses the Maryland Archaeological Conservation Laboratory (MAC Lab), as well as a library with archaeological research material. JPPM also hosts several web pages that showcase Maryland archaeology and databases to assist researchers in artifact identification. JPPM's and MHT's archaeology programs sponsor numerous educational activities throughout the year. To learn more about MHT programs, click on the boxes below.
