The State Circle well, discovered during the larger State Circle archaeological investigatons, is believed to be a late 18th-century public well. The moist environment of a well preserves ceramic, glass, metal, and organic material. It was hoped that intact 18th and 19th centuiy domestic deposits were preserved in the well shaft. Because of time constraints, a three-inch diameter core was extracted from the well shaft, which extended thirty-five feet below surface. The results of the coring process enabled archaeologists to make a final decision not to excavate the well shaft. Historical documentation showed that the well was covered and had a pump and was still in use around 1900. The well had been filled in early in the 20th century with soil brought in from elsewhere.
