its common for bottles to be found this way , often new home construction especially when they clear the old farms to make way for new homes or tear up old lots in the city for new condo buildings , often they find old bottles in the process . or road construction when they expand the roads as older roads were often smaller and as they expand they tear up the old ditches where bottles were hiding . I'd say your right most of they are from 60's or 70's era but could be older stuff there if dump goes deeper or older areas somewhere else on property
