noted for its inaccessibility.

"The shape of the cliff would easily suggest the idea of a
massive serpent, and with this inaccessibility to the spot would
produce a peculiar feeling of awe, as if it were a great Manitou
which resided there, and so a sentiment of wonder and worship
would gather around the locality. This would naturally give rise
to a tradition or would lead the people to revive some familiar
tradition and localize it. This having been done, the next step
would be to erect an effigy on the summit which would both
satisfy the superstition and represent the tradition. It would
then become a place where the form of the serpent divinity was
plainly seen, and where the worship of the serpent, if it could
be called worship, would be practiced. Along with this serpent
worship, however, there was probably the formality instituted
here, and the spot made sacred to them. It was generally
'sacrificing in a high place,' the fires which were lighted
would be seen for a great distance down the valley and would
cast a glare over the whole region, producing a feeling of awe
in the people who dwelt in the vicinity. The shadows of the
cliff would be thrown over the valley, but the massive form of
the serpent would be brought out in bold relief; the tradition
would be remembered and superstition would be aroused, and the
whole scene would be full of strange and awful associations."

The various authors who have treated of this serpent mound have
maintained that the tradition which found its embodiment here
was the old Brahmanic tradition of the serpent and the egg. Even
the Indians had their traditions in regard to the meaning of
various symbols.
