Each summer, public archaeology programs give volunteers the chance to see what it is like to be an archaeologist and excavate an actual site. Such programs are conducted by the Department of Anthropology, University of Maryland College Park; the Department of Sociology, Washington College; Historic London Town and Gardens; Historic St. Mary's City; Jefferson Patterson Historical Park and Museum; and Maryland-National Capital Park and Planning Commission.
