Site 21 is a relatively small site located just east of the Bell Field rock alignment. During the 1997 Plantation Archaeological Survey, one test pit on the 40-foot grid contained a wrought nail. A more intensive sampling program was scheduled for the 1999 survey season. Test pits on 20-foot centers were placed around the positive test pit. A number of positive test pits were identified and the 20-foot grid was expanded. A total of 29 positive test pits were identified and 59 artifacts were recovered. The assemblage was domestic in nature, consisting of refined ceramics including pearlware, creamware, and British Brown stoneware. Other artifacts found at Site 20 include wrought nails and a wrought spike.
