I have recently discovered a cistern behind my house. Evidence indicates that it was probably constucted at the same time as the dwelling - 1672. Having picked 1759 as the site interpretation date, what would an appropriate structure look like at the cistern mouth? It is presently level with the ground and capped with a 3'x3' stone. The inner walls are granite fieldstone with three courses of 17th century bricks just below the gound level. The bricks are mortared with clay. If the cistern is reopened, should it be examined for artifacts and plant remnants, or left alone for future archaeologists? My field of knowledge is in 17th and 18th century carpentry, and although I have received training in archeology I could not do as propper an analysis as a professional. All suggestions are welcome.
