2024 Tyler Bastian Field Session

Oldtown I (18AG9)
31 May - 10 June, 2024


The 2024 Tyler Bastian Field Session in Maryland Archeology will be held at the Oldtown I archeological site (18AG9), near Oldtown, Maryland, from 31 May - 10 June, 2024.

The Field Session will follow-up on both a geophysical remote sensing survey directed by the MHT Office of Archaeology in November of 2020 (which identified several anomalies of interest), and brief ground-truthing excavations conducted in October of 2023. The 2023 excavations revealed the presence of remarkably intact domestic features with an approximate date range of 1750-1790 suggesting that they relate to the 18th-century fort and dwelling of Colonel Thomas Cresap (a.k.a. the “Maryland Monster”).

Thomas Cresap is one of the most important frontiersmen in Maryland and American history. He played a major role in land speculation, both at the northern and western boundaries of Maryland. He played a role, along with the Delaware Indian, Nemacolin, in blazing a setler’s road across the Alleghany Mountains west to the Ohio Valley. He was heavily involved in the fur trade and sometime friend and sometime foe of the Native American inhabitants of western Maryland and the Ohio Valley. He played host at his home in Oldtown to General Edward Braddock, George Washington, and other important dignitaries from the three English colonies of Virginia, Maryland, and Pennsylvania, as well as from numerous Indian Nations. His home was a refuge for colonists fleeing attacks during both the French and Indian War and Pontiac’s War that followed. And he was an early opponent of British policy in the west, opposition to which would eventually play a role in the American Revolution (in which his son, Michael Cresap would play a major role).

Site 18AG9 appears to be his dwelling based on both archival evidence and the dating of the artifacts recently recovered. While prior research in 2009/2010 helped to identify 18AG9 as the leading candidate site for Cresap’s fortified home, the present project is the first to document intact archaeological features suggestive of structures domestic in nature. The overall goals of the project are:

  • Obtain data sufficient to support a determination of eligibility and likely an individual nomination to the National Register of Historic Places for 18AG9,
  • Make management recommendations to C & O Canal National Historical Park regarding the identified resources, and
  • Obtain information that can be utilized by NPS for public interpretation of the resource

The Field Session is held in cooperation with the Maryland Historic Trust's Office of Archeology. The purpose of the Field Session is to introduce lay persons to archeological methods and to teach Maryland's past through hands-on involvement while making meaningful contributions to the study of Maryland archeology. MHT, Office of Archeology staff will provide professional oversight of volunteers at the site and will work to produce a final scientific report for the National Park Service.

In addition to the contributions of the ASM, funding for this project was provided in part by Preservation Maryland and the Maryland Historical Trust.


- Field Session Lecture Schedule -

ASM has traditionally presented a number of lectures during the annual field session.

A schedule of lectures will be posted here as soon as it is available.
