From a blog called "Ruminations from the distant hills".
Interesting picture of a fish weir and some modern rock piles in the river. But this line caught my attention:
..."Uktena, in case you’ve not seen one lately, is a monstrous snake, as big around as a tree trunk, with horns on its head, a bright, blazing crest like a diamond on its forehead"
Just yesterday I was wondering if any Native American mythin includes a horned monster with something white on its head. Because that "horned creature" [click here] looked to me to be part of a myth construction. So I looked up Uktena online. Here is a representative result. It seems that this particular version of the "horned serpent" is a Cherokee one and, of course, suburban Westford is not the Cherokee area.
