Premise 01

If the stone wall begins with something that resembles a snake's head,

then there is a high degree of possibility that it may be

an Indigenous construction worthy of further investigation.

Or maybe:

   If the Qusuqaniyutók (‘stone row, enclosure’ Harris and Robinson, 2015 :140, ‘fence that crosses back’ viz. qussuk, ‘stone,’ Nipmuc or quski, quskaca, ‘returning, crosses over,’ qaqi, ‘runs,’ pumiyotôk, ‘fence, wall,’ Mohegan, Mohegan Nation 2004:145, 95, 129), begins with the head of  Gitaskog - or Tatoskok - Gtaskog, Kitaskog, Kita-skog, Keeta-skog, Gitaskog, Giciskog, Gichi-skog, or Msaskog, Msa-skog, Tatoskog, Tatoskok, Pita-skog, Peeta-skog, Peetaskog, Jipijka'm, Jupijkám, Tcipitckaam, Chipitchkam, Chepitchcalm, Kchi Pitchkayam, Ktchi Pitchkaam, Chepechcalm, Chepichkaam, Chepitchkaam, Che-Pitch-Calm, Chepichealm, Jibichkam, Jipijkma, Chepitkam, Ktchi-Pitchkayam, Kci-Athussos, Kitchi-at'Husis, Kici Atthusus, Kichi-Athusoss, K'cheattosis, Ktchi at'husis, Atosis, Mishiginebig, Mishi-Ginebig, Meshkenabec, Msi-Knebik, Kichikinebik, Kichiginebig, Mishi-Kinebig, Mishikinebik, Misikinebik, Meshkenabec, Mshignebig, Kchiknebig, Mshiknebik, Kchiknebik, Kichiknebik, Kchiknebig, Kchiginebig, Mshiginebig, Misi-Ginebig,

    "...a type of mythological freshwater serpent common to many tribes of the eastern United States and Canada...usually described as huge, scaly, dragon-like serpents with horns and long teeth...possessing magical abilities such as shape-shifting, invisibility, or hypnotic powers; bestowing powerful medicine upon humans who defeat them or help them; controlling storms and weather, and so on...venerated as gods or spirit beings in some tribes..." then it is most likely an Indigenous construction worthy of further investigation.
