New to this site and I have so many questions. Always have picked up rocks but really starting to understand and reading more about my heritage to teach my kids but a true newbie Always loved this rock because of the carved lines but it's broken and not sure what it is?
Welcome to Treasurenet and to the Native American Artifacts forum as well. I can only tell you what it isn't....a Native American artifact. It's a cool looking rock though!
It is a natural stone, the line was made due to a softer part of the stone eroding away before the other. keep looking, from your other post you are on the right track
