I know it is hard to take the news that what you have found is not an artifact, but all artifact hunters in the first days and times have found things we all thought was an artifact, only to be told by someone with time under their belt that it was not. Sometimes it takes people a year or more before they can spot something modern compared to a relic. You have to study artifacts of all types, stone working and anything to do with Native Americans and put time and more time in the field. There are a lot of people on here that know what they are talking about. I have been collecting well over 38 years and I still don't know it all and never will, and I still post things to get other ideas about an item ( another set of eyes are always better). For example I had a item that I had for over 4 years and knew it wasn't a modern item, but did not know what it was. Then I found this site and posted it on here and found out it was an egg stone, used in a Bolo. It was just something I had never seen before, but looking at it I could tell it was not modern. Once you learn how to spot something that has been altered by man compared to something made by nature or by modern man, it will be a moment of awaking. When you put something on a site and it goes all over the world ,you may get some comments you don't like, but try not to be thin skinned about what people post. Most are stating what they see from a photo and do not mean any harm by what they say. As a rule if something is to uniform, and has to many straight lines and so on then it is modern. The eye can play all types of tricks on you and has for finding something away from where you think no one has been before, take my word there are very few places in the USA that someone has not been and dropped trash.JMO
