New to the forum and bottle digging and look forward to learning from you all. One thing I’ve got in my mind I want to try my hand at is finding old railroad dump sites. In my area one of the oldest things to be found are the railroads. I’ve started walking them and found some neat insulators and a few odds and ends here and there. My question is are general rules of thumb to look for dump sites? Were they near the last stop before a city, in the middle of nowhere far away from cities, near water so that they could get water when dumping, etc.. I know a lot of this will be walking and probing, but curious of ideas to narrow it down some.
