I have some cabins that were built in the 30s. When I got my detector I thought for sure I'd find some silver by now but no luck. I hit it up yesterday for about 30 minutes and found two newer quarters, 2000s, and they were buried about 5 or 6 inches. They are located on a river and it floods in the spring but nothing intense, just a little bit of water covering the ground. So if things were lost over 60 years ago than who knows how deep it will be. any suggestions or will that treasure be buried for good. The other bad part is that all the cables are buried underground so my detector go nuts. So i have to hunt near the river in front of the cabins.
