30 Unusual Archaeological Finds In The US We Still Can’t Explain

24. STRANGE CARVED STONE

Our ancient ancestors seem to have wanted to share something through the things they made. Carved images in stones are famous around the world, and a rock shaped like an egg was discovered in 1872 in New Hampshire, near Lake Winnipesaukee. It’s still a mystery, though, since the measurements are perfect and there’s still a debate who made the stone. One theory states it was made by Native Americans and used as a peace treaty between two tribes and others say it could’ve been a tool.
