No, there are no lists of dumps sites. I wish it were that easy. I've been a bottle digger/collector since 1969 and I can tell you, it takes a LOT of researching, searching and exploring. Look for old areas where old houses are/were, woods, fields, along creeks, under old bridges, etc. You'll need a bottle probe to help you find where those buried treasures are. I found my first bottles with a beginner "toy" detector by scanning old yards. Check depressions in yards and woods, as many times those are trash pits that settled and sank through the years. Look for glass, pottery and metal shards on the surface too. You will find a lot of bottles out there, but finding the "good" ones takes more effort. Peruse some of the online bottle sites and learn as much as you can to know what bottles are the collector type. Also look at old posts on this very forum, as there's tons of good info. here too. I have many bottles I've found in my albums on here as well. Most importantly, don't be afraid to ask questions, that's how you "find out". Try to link up with other bottle diggers/collectors in your area. Look at online digging videos. And take your time learning. Don't burn yourself out as some have on here. Good luck!
