An 18th-century oak dogshore (a temporary support for a ship just before launching) was recently extracted from one of the lab freezers where it has been freeze-drying, as the last phase of its treatment, since 2002. Because of the size and shape of this artifact, it would not fit into the lab’s vacuum freeze-drier (even though it is the largest archaeological freeze-drier on the east coast!), and so it had to be freeze-dried the “old-fashioned” way. The dogshore comes to us from the Steward Shipyard, which was located in Anne Arundel County. The shipyard, one of colonial Maryland’s most important shipbuilding sites, was excavated by the Archeological Society of Maryland during their 1993 field session.
