I am not a professional or experienced archaeologist. I have just been collecting and researching since May of 2009. I still need to learn much more about the ancient cultures to better understand the purpose of these tools and effigies. I also need to learn about local geology in order to determine which rocks are not of local origin. Since this site was certainly a settlement, one must assume that any rock that seems oddly shaped, unnatural in appearance or not of local origin is a potential artifact. Of course one must also stockpile every rock from the area of the site for re-examination as knowledge increases and new evidence is discovered. If you have any insight into a site like this or have seen rocks similar in form to those pictured, please, by all means share your knowledge and I will reciprocate. None of my artifacts are for sale and I am not in this for any monetary reward. I eventually hope to have a collection significant enough to be placed into a local museum.
