To all - While I don't know for sure, that animal image might be of an Underwater Panther. I have many Native friends in New England (mostly Abenaki in VT) and they have an image that is similar to that. The Underwater Panther is a powerful entity. I won't go into it too much but traditionally a little white dog would be tossed into the maelstrom while on the water to calm the waters produced by him/it; at least that's my understanding of the situation.
That's all for now. Take care and until next time...Be well.
The horned guy is Misshepissu, the Great Lynx, know in this neck of the woods as the controller of water, usually somewhat malevolent. The serpent like things with him are his minions. We often make a tobacco offering before crossing a big lake, and always at pictograph sites. I'll usually take my chances on the lakes if smokes are running low, but i won't chance it at pictograph sites.
