Dear Debbie, are you dealing with individual farmsteads or communities? I know of one community that some researchers, at New Mexico State University, were interested in excavating, at one time, but had not finalized any plans. The community was called Blackdom and was located in southern New Mexico (to the best of my recolection). I do believe that some research was conducted, but am not sure exactly what was done. What I do remember is that the community was founded after the Civil War, but was abandoned. I would suggest you contact Dr. Ed Staski at NMSU, he's in the directory for the Society for Historical Archaeology members. Hope this helps. Joanne Reiter
