There are several problems with this effigy. It was only found 2 weeks ago. Some reports are coming out that they are testing the “scales” of the formation to see if it is a fossil. The implications of this are endless. There is also a myth of a “god-king” who was turned into a giant snake due to what he did to a village. The story has yet to be confirmed, but always good to read about Eastern myths of plumed serpents.
The head which appears above is not a part of the Cave structure but consists of a different geological formation in Laos. Sources are scarce and some claim they are the same structure. I welcome all to criticize, propose thoughts, as well as source hunt! With all this being said even if this formation is natural I would propose this (as well as other Asian Geological Formations) for inspiration of the Naga Myth. Then again we must remember that pre-WW2 as well as during WW2 something drew Nazi Germany to Asia. Have fun and be nice!
