Ever wonder what happens if you actually found a buried treasure or some sort of National Treasure-esk haul of ancient loot? Yet through the precise mapping and identification of objects, archæological sites can be identified, which can later be dug out by archæologists. Certain states use old English common law which includes the treasure trove law. A problem arises when amateur treasure hunters just dig up archæological sites, armed with metal detectors to find valuable artifacts like golden brooches or coins. This activity is highly damaging to archæological sites to the point of making the sites worthless for research.
