These tablets were found on a remote ranch in West Texas in the early 1960's. My dad found them, and did not want to draw any attention to himself, so simply put then in a safety deposit box, where they sat the last almost 40 years. When he died, I ended up with them. These are really peculiar markings. They are nothing like the typical Native American artifacts found in the region. There are numerous pre-indian "Mounds" in the area, but these are the only stone tablets ever found in the area. We have had great difficulty getting any information or interpretation of what these tablets represent. Any ideas or leads would be appreciated.
