Here is the deal, I am a avid scuba diver and bottle collector. Does anyone have locations of any old (pre 1950) coastal gold mines, canerys, or other facilities that are now abandoned and have docks or piers that are still recognizable? I have found these are great places to find old bottles and other items that were once considered trash but are fun to find. Myseld and some others are always looking for new dive sites. I will happily post any pictures of our finds.
