This report presents the findings of a research-oriented archaeological survey and excavations conducted at the site 36LU331. The University of Maryland Department of Anthropology field school, under the direction of Dr. Paul A. Shackel, conducted this research during the summer of 2016 in accordance with the Pennsylvania Historic and Museum Commission’s “Letter of Authorization” agreement signed January 29, 2016 (Appendix C). A combination Phase I shovel test survey and surface survey was conducted on the PHMC- owned portion of Back Street in June 2015. This preliminary research indicated that House 34/36, House 38/40, and House 42/44, previously unrecorded archaeological sites, needed to be registered with the Pennsylvania State Historic Preservation Office. These sites are designated as 36LU331, 36LU332, and 36LU333, respectively; however, for the 2016 summer field season, only 36LU331 was selected for further evaluation. As a result of the intact archaeological remains at 36LU331, the site is eligible for the National Register of Historic Places (NRHP). It is not currently included within the bounds of the Eckley Historic District, which was listed on the NRHP on October 26, 1971. It is recommended that the National Register boundaries be redrawn to include site 36LU331 and that the site be added as a contributing resource to the nomination under Criterion D, a place that has yielded, or may be likely to yield, information important in prehistory or history.
