Im not saying this is old but just sharing info which nullifies one aspect IMO. They 1860s jar I sold last year had virtually NO wear on the bottom and was a wax sealer utility jar.
Dug two 4-5 foot test holes today. First one I saw a glistening of 20-30s glass on top. First 1-2 feet were rusty and glass chunks and even had a nice rock with a lot of mortarish material on it. All 20-30s glass though. Deeper was nothing. Other suspect spot was clean the whole way. Went back...
PS Here is my secret Bottlehoe. In my finds in these rivers. The best ones were invisible. Under 3 or 4 inches of mud. That includes a real nice jar circa 1868. Bring gloves.
In between that 225 yards is one of the oldest main highways around. Maybe a small church? Maybe a stop station for travelers that the homeowner across highway ran?
