(And a Canthal or Two? An Ulstĭtlĭ'?)
When it comes to making observations about how to decide if a flat topped triangular boulder, especially one with some smaller stones added on top, might be an Indigenous Ceremonial Stone Landscape Feature, I first recall that the rattlesnake associated with Great Serpents has a triangular head (and wonder if there is a stone body under all that debris) I look for a suggestion of an eye, especially when accompanied by the suggestion of other fairly accurate details such as snake scales, especially the supraocular scale above a rattlesnake's eye - and Great Serpent's Eye. Sometimes it's a natural feature, sometimes there's a fracture that makes me suspicion of human enhancement, something subtracted from the stone, sculpted rather than quarried, maybe even polished smooth as well. Adding stones could very well be another variation (having seen some combinations of boulders and stones used in other places). When viewed just right, this placement could suggest the light colored stone as an eye and behind it another stone that somewhat resembles the supraocular on its upper surface while another face of the same stone invite images of other scales behind the eye.
This only occurred to me when I saw a small sized image of this one above.
Suddenly, the stone becomes the Strong Looker...
(And compare the shapes of the two other stones to canthal scales.)

And then: I peeked under the pine needles...
...the red color is more "vivid" when seen in person.
Could it be an ulstĭtlĭ'?
And these are the first few images I took, "just because."
Shaping in a similar style?
