“This is a serpent effigy - and the serpent effigies are quite often in dispute because the presumption is that they are stone walls. Most often, they are too low to pen anything in, but we identify them by other means. Usually they do have a head, such as the one you see here. This particular one, just behind the head, also has a space and an orange stone, because we believe that they are related to the serpent effigy that is in the area of Scorpius that the Cherokee referred to as the Uktena, that is, a serpent with an orange stone. In its terra form, it’s (it has) a jewel and it is horned, but this is, as below, so above...”

Note: DH is likening the Orange stone (as below/in the stone "wall") to the orange colored bright star Antares that is the Jewel on the head of the Great Serpent constellation (as above in the sky), part of what Europeans came to call Scorpius.
"Those who know say the Uktena is a great snake, as large around as a tree trunk, with horns on its head, and a bright blazing crest like a diamond on its forehead, and scales glowing like sparks of fire. It has rings or spots of color along its whole length, and can not be wounded except by shooting in the seventh spot from the head, because under this spot are its heart and its life. The blazing diamond is called Ulun'suti—"Transparent"—and he who can win it may become the greatest wonder worker of the tribe. But it is worth a man's life to attempt it, for whoever is seen by the Uktena is so dazed by the bright light that he runs toward the snake instead of trying to escape. As if this were not enough, the breath of the Uktena is so pestilential, that no living creature can survive should they inhale the tiniest bit of the foul air expelled by the Uktena. Even to see the Uktena asleep is death, not to the hunter himself, but to his family." - James Mooney Myths of the Cherokee
