a new bob is on the bob page. We started with one of these, now we have five and still no idea what they are. They appear to be cylindrical in shape, of ceramic with a lead coating outside. Some are closed, some have some kind of concrete inside.
When you do not know, we ask. Today we located at AC7, three very interesting concretions which we were unable to understand.
Because this will not be the last time, the P.I. decided to open a page dedicated to these BOBs for anyone, if recognize the shapes can contact us.
Happy viewing in the BOB page.
